Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47402, here are decompositions:

  • 13 + 47389 = 47402
  • 109 + 47293 = 47402
  • 151 + 47251 = 47402
  • 181 + 47221 = 47402
  • 241 + 47161 = 47402
  • 283 + 47119 = 47402
  • 409 + 46993 = 47402
  • 541 + 46861 = 47402

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 47402 first appears in π at position 71,659 of the decimal expansion (the 71,659ordinal-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.
