Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515854, here are decompositions:

  • 11 + 515843 = 515854
  • 41 + 515813 = 515854
  • 71 + 515783 = 515854
  • 83 + 515771 = 515854
  • 113 + 515741 = 515854
  • 167 + 515687 = 515854
  • 173 + 515681 = 515854
  • 191 + 515663 = 515854

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 515,854 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 515854 first appears in π at position 978,213 of the decimal expansion (the 978,213ordinal-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.
