Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 506666, here are decompositions:

  • 3 + 506663 = 506666
  • 19 + 506647 = 506666
  • 37 + 506629 = 506666
  • 67 + 506599 = 506666
  • 73 + 506593 = 506666
  • 103 + 506563 = 506666
  • 337 + 506329 = 506666
  • 397 + 506269 = 506666

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 506,666 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 506666 first appears in π at position 996,928 of the decimal expansion (the 996,928ordinal-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.
