Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71504, here are decompositions:

  • 31 + 71473 = 71504
  • 61 + 71443 = 71504
  • 67 + 71437 = 71504
  • 151 + 71353 = 71504
  • 157 + 71347 = 71504
  • 163 + 71341 = 71504
  • 211 + 71293 = 71504
  • 241 + 71263 = 71504

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 71504 first appears in π at position 46,102 of the decimal expansion (the 46,102ordinal-suffix:nd 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.
