Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512200, here are decompositions:

  • 53 + 512147 = 512200
  • 107 + 512093 = 512200
  • 179 + 512021 = 512200
  • 191 + 512009 = 512200
  • 239 + 511961 = 512200
  • 389 + 511811 = 512200
  • 443 + 511757 = 512200
  • 509 + 511691 = 512200

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 512,200 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 512200 first appears in π at position 587,788 of the decimal expansion (the 587,788ordinal-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.
