Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511526, here are decompositions:

  • 3 + 511523 = 511526
  • 7 + 511519 = 511526
  • 19 + 511507 = 511526
  • 73 + 511453 = 511526
  • 79 + 511447 = 511526
  • 109 + 511417 = 511526
  • 139 + 511387 = 511526
  • 193 + 511333 = 511526

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 511,526 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 511526 first appears in π at position 47,581 of the decimal expansion (the 47,581ordinal-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.
