Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511910, here are decompositions:

  • 13 + 511897 = 511910
  • 19 + 511891 = 511910
  • 37 + 511873 = 511910
  • 43 + 511867 = 511910
  • 67 + 511843 = 511910
  • 79 + 511831 = 511910
  • 109 + 511801 = 511910
  • 199 + 511711 = 511910

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 511,910 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 511910 first appears in π at position 261,332 of the decimal expansion (the 261,332ordinal-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.
