Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 537640, here are decompositions:

  • 3 + 537637 = 537640
  • 29 + 537611 = 537640
  • 41 + 537599 = 537640
  • 53 + 537587 = 537640
  • 71 + 537569 = 537640
  • 113 + 537527 = 537640
  • 227 + 537413 = 537640
  • 239 + 537401 = 537640

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 537,640 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 537640 first appears in π at position 824,602 of the decimal expansion (the 824,602ordinal-suffix:nd 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.
