Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515950, here are decompositions:

  • 89 + 515861 = 515950
  • 107 + 515843 = 515950
  • 137 + 515813 = 515950
  • 167 + 515783 = 515950
  • 173 + 515777 = 515950
  • 179 + 515771 = 515950
  • 257 + 515693 = 515950
  • 263 + 515687 = 515950

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 515,950 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 515950 first appears in π at position 329,592 of the decimal expansion (the 329,592ordinal-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.
