Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78404, here are decompositions:

  • 3 + 78401 = 78404
  • 37 + 78367 = 78404
  • 97 + 78307 = 78404
  • 103 + 78301 = 78404
  • 127 + 78277 = 78404
  • 163 + 78241 = 78404
  • 211 + 78193 = 78404
  • 241 + 78163 = 78404

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 78404 first appears in π at position 18,586 of the decimal expansion (the 18,586ordinal-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.
