Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65480, here are decompositions:

  • 31 + 65449 = 65480
  • 43 + 65437 = 65480
  • 61 + 65419 = 65480
  • 67 + 65413 = 65480
  • 73 + 65407 = 65480
  • 109 + 65371 = 65480
  • 127 + 65353 = 65480
  • 157 + 65323 = 65480

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 65480 first appears in π at position 142,147 of the decimal expansion (the 142,147ordinal-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.
