Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71200, here are decompositions:

  • 29 + 71171 = 71200
  • 47 + 71153 = 71200
  • 53 + 71147 = 71200
  • 71 + 71129 = 71200
  • 131 + 71069 = 71200
  • 251 + 70949 = 71200
  • 263 + 70937 = 71200
  • 281 + 70919 = 71200

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 71200 first appears in π at position 234,073 of the decimal expansion (the 234,073ordinal-suffix:rd 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.
