Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77200, here are decompositions:

  • 29 + 77171 = 77200
  • 47 + 77153 = 77200
  • 59 + 77141 = 77200
  • 107 + 77093 = 77200
  • 131 + 77069 = 77200
  • 197 + 77003 = 77200
  • 239 + 76961 = 77200
  • 251 + 76949 = 77200

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 77200 first appears in π at position 12,122 of the decimal expansion (the 12,122ordinal-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.
