Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 49440, here are decompositions:

  • 7 + 49433 = 49440
  • 11 + 49429 = 49440
  • 23 + 49417 = 49440
  • 29 + 49411 = 49440
  • 31 + 49409 = 49440
  • 47 + 49393 = 49440
  • 71 + 49369 = 49440
  • 73 + 49367 = 49440

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 49440 first appears in π at position 32,565 of the decimal expansion (the 32,565ordinal-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.
