Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71418, here are decompositions:

  • 5 + 71413 = 71418
  • 7 + 71411 = 71418
  • 19 + 71399 = 71418
  • 29 + 71389 = 71418
  • 31 + 71387 = 71418
  • 59 + 71359 = 71418
  • 71 + 71347 = 71418
  • 79 + 71339 = 71418

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 71418 first appears in π at position 31,139 of the decimal expansion (the 31,139ordinal-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.
