Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 479440, here are decompositions:

  • 11 + 479429 = 479440
  • 53 + 479387 = 479440
  • 83 + 479357 = 479440
  • 113 + 479327 = 479440
  • 131 + 479309 = 479440
  • 173 + 479267 = 479440
  • 197 + 479243 = 479440
  • 239 + 479201 = 479440

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 479,440 and was likely granted around 1892.

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

Position in π

The digit sequence 479440 first appears in π at position 206,287 of the decimal expansion (the 206,287ordinal-suffix:th 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.
