Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47040, here are decompositions:

  • 23 + 47017 = 47040
  • 43 + 46997 = 47040
  • 47 + 46993 = 47040
  • 83 + 46957 = 47040
  • 107 + 46933 = 47040
  • 139 + 46901 = 47040
  • 151 + 46889 = 47040
  • 163 + 46877 = 47040

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 47040 first appears in π at position 10,745 of the decimal expansion (the 10,745ordinal-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.
