Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511286, here are decompositions:

  • 7 + 511279 = 511286
  • 43 + 511243 = 511286
  • 73 + 511213 = 511286
  • 109 + 511177 = 511286
  • 163 + 511123 = 511286
  • 199 + 511087 = 511286
  • 229 + 511057 = 511286
  • 367 + 510919 = 511286

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 511,286 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 511286 first appears in π at position 199,435 of the decimal expansion (the 199,435ordinal-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.
