Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 557640, here are decompositions:

  • 7 + 557633 = 557640
  • 29 + 557611 = 557640
  • 67 + 557573 = 557640
  • 73 + 557567 = 557640
  • 89 + 557551 = 557640
  • 103 + 557537 = 557640
  • 107 + 557533 = 557640
  • 151 + 557489 = 557640

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 557,640 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 557640 first appears in π at position 430,020 of the decimal expansion (the 430,020ordinal-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.
