Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581012, here are decompositions:

  • 31 + 580981 = 581012
  • 43 + 580969 = 581012
  • 73 + 580939 = 581012
  • 199 + 580813 = 581012
  • 349 + 580663 = 581012
  • 373 + 580639 = 581012
  • 379 + 580633 = 581012
  • 463 + 580549 = 581012

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 581,012 and was likely granted around 1896.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 581012 first appears in π at position 840,215 of the decimal expansion (the 840,215ordinal-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.
