Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516138, here are decompositions:

  • 11 + 516127 = 516138
  • 47 + 516091 = 516138
  • 61 + 516077 = 516138
  • 89 + 516049 = 516138
  • 197 + 515941 = 516138
  • 251 + 515887 = 516138
  • 277 + 515861 = 516138
  • 281 + 515857 = 516138

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 516,138 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 516138 first appears in π at position 45,525 of the decimal expansion (the 45,525ordinal-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.
