Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545542, here are decompositions:

  • 59 + 545483 = 545542
  • 113 + 545429 = 545542
  • 251 + 545291 = 545542
  • 311 + 545231 = 545542
  • 353 + 545189 = 545542
  • 401 + 545141 = 545542
  • 449 + 545093 = 545542
  • 479 + 545063 = 545542

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 545,542 and was likely granted around 1895.

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

Position in π

The digit sequence 545542 first appears in π at position 191,421 of the decimal expansion (the 191,421ordinal-suffix:st 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.
