Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40650, here are decompositions:

  • 11 + 40639 = 40650
  • 13 + 40637 = 40650
  • 23 + 40627 = 40650
  • 41 + 40609 = 40650
  • 53 + 40597 = 40650
  • 59 + 40591 = 40650
  • 67 + 40583 = 40650
  • 73 + 40577 = 40650

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 40650 first appears in π at position 64,905 of the decimal expansion (the 64,905ordinal-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.
