Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511884, here are decompositions:

  • 11 + 511873 = 511884
  • 17 + 511867 = 511884
  • 41 + 511843 = 511884
  • 53 + 511831 = 511884
  • 73 + 511811 = 511884
  • 83 + 511801 = 511884
  • 97 + 511787 = 511884
  • 127 + 511757 = 511884

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 511,884 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 511884 first appears in π at position 41,981 of the decimal expansion (the 41,981ordinal-suffix:st 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.
