Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510780, here are decompositions:

  • 7 + 510773 = 510780
  • 13 + 510767 = 510780
  • 29 + 510751 = 510780
  • 71 + 510709 = 510780
  • 73 + 510707 = 510780
  • 89 + 510691 = 510780
  • 97 + 510683 = 510780
  • 103 + 510677 = 510780

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 510,780 and was likely granted around 1893.

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

Position in π

The digit sequence 510780 first appears in π at position 134,816 of the decimal expansion (the 134,816ordinal-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.
