Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511418, here are decompositions:

  • 31 + 511387 = 511418
  • 67 + 511351 = 511418
  • 139 + 511279 = 511418
  • 157 + 511261 = 511418
  • 181 + 511237 = 511418
  • 241 + 511177 = 511418
  • 307 + 511111 = 511418
  • 331 + 511087 = 511418

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 511,418 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 511418 first appears in π at position 32,924 of the decimal expansion (the 32,924ordinal-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.
