Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518444, here are decompositions:

  • 13 + 518431 = 518444
  • 103 + 518341 = 518444
  • 211 + 518233 = 518444
  • 307 + 518137 = 518444
  • 313 + 518131 = 518444
  • 331 + 518113 = 518444
  • 397 + 518047 = 518444
  • 463 + 517981 = 518444

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 518,444 and was likely granted around 1894.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 518444 first appears in π at position 514,863 of the decimal expansion (the 514,863ordinal-suffix:rd digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
