Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47812, here are decompositions:

  • 3 + 47809 = 47812
  • 5 + 47807 = 47812
  • 71 + 47741 = 47812
  • 101 + 47711 = 47812
  • 113 + 47699 = 47812
  • 131 + 47681 = 47812
  • 173 + 47639 = 47812
  • 269 + 47543 = 47812

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 47812 first appears in π at position 32,848 of the decimal expansion (the 32,848ordinal-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.
