Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47290, here are decompositions:

  • 3 + 47287 = 47290
  • 11 + 47279 = 47290
  • 53 + 47237 = 47290
  • 83 + 47207 = 47290
  • 101 + 47189 = 47290
  • 167 + 47123 = 47290
  • 179 + 47111 = 47290
  • 197 + 47093 = 47290

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 47290 first appears in π at position 59,038 of the decimal expansion (the 59,038ordinal-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.
