Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511312, here are decompositions:

  • 23 + 511289 = 511312
  • 89 + 511223 = 511312
  • 101 + 511211 = 511312
  • 149 + 511163 = 511312
  • 251 + 511061 = 511312
  • 293 + 511019 = 511312
  • 311 + 511001 = 511312
  • 509 + 510803 = 511312

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 511,312 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 511312 first appears in π at position 430,582 of the decimal expansion (the 430,582ordinal-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.
