Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511804, here are decompositions:

  • 3 + 511801 = 511804
  • 11 + 511793 = 511804
  • 17 + 511787 = 511804
  • 47 + 511757 = 511804
  • 101 + 511703 = 511804
  • 113 + 511691 = 511804
  • 173 + 511631 = 511804
  • 263 + 511541 = 511804

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 511,804 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 511804 first appears in π at position 467,369 of the decimal expansion (the 467,369ordinal-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.
