Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71524, here are decompositions:

  • 41 + 71483 = 71524
  • 53 + 71471 = 71524
  • 71 + 71453 = 71524
  • 113 + 71411 = 71524
  • 137 + 71387 = 71524
  • 191 + 71333 = 71524
  • 197 + 71327 = 71524
  • 263 + 71261 = 71524

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 71524 first appears in π at position 114,131 of the decimal expansion (the 114,131ordinal-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.
