Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558666, here are decompositions:

  • 5 + 558661 = 558666
  • 23 + 558643 = 558666
  • 37 + 558629 = 558666
  • 67 + 558599 = 558666
  • 79 + 558587 = 558666
  • 83 + 558583 = 558666
  • 103 + 558563 = 558666
  • 127 + 558539 = 558666

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 558,666 and was likely granted around 1895.

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

Position in π

The digit sequence 558666 first appears in π at position 454,657 of the decimal expansion (the 454,657ordinal-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.
