Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511508, here are decompositions:

  • 31 + 511477 = 511508
  • 61 + 511447 = 511508
  • 157 + 511351 = 511508
  • 181 + 511327 = 511508
  • 211 + 511297 = 511508
  • 229 + 511279 = 511508
  • 271 + 511237 = 511508
  • 307 + 511201 = 511508

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 511,508 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 511508 first appears in π at position 517,544 of the decimal expansion (the 517,544ordinal-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.
