Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78004, here are decompositions:

  • 5 + 77999 = 78004
  • 53 + 77951 = 78004
  • 71 + 77933 = 78004
  • 137 + 77867 = 78004
  • 191 + 77813 = 78004
  • 257 + 77747 = 78004
  • 281 + 77723 = 78004
  • 293 + 77711 = 78004

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 78004 first appears in π at position 45,261 of the decimal expansion (the 45,261ordinal-suffix:st 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.
