Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64080, here are decompositions:

  • 13 + 64067 = 64080
  • 17 + 64063 = 64080
  • 43 + 64037 = 64080
  • 47 + 64033 = 64080
  • 61 + 64019 = 64080
  • 67 + 64013 = 64080
  • 73 + 64007 = 64080
  • 83 + 63997 = 64080

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 64080 first appears in π at position 18,506 of the decimal expansion (the 18,506ordinal-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.
