Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65020, here are decompositions:

  • 17 + 65003 = 65020
  • 23 + 64997 = 65020
  • 83 + 64937 = 65020
  • 101 + 64919 = 65020
  • 149 + 64871 = 65020
  • 167 + 64853 = 65020
  • 227 + 64793 = 65020
  • 239 + 64781 = 65020

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 65020 first appears in π at position 32,045 of the decimal expansion (the 32,045ordinal-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.
