Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515706, here are decompositions:

  • 5 + 515701 = 515706
  • 13 + 515693 = 515706
  • 19 + 515687 = 515706
  • 29 + 515677 = 515706
  • 43 + 515663 = 515706
  • 53 + 515653 = 515706
  • 67 + 515639 = 515706
  • 109 + 515597 = 515706

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 515,706 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 515706 first appears in π at position 156,295 of the decimal expansion (the 156,295ordinal-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.
