Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71470, here are decompositions:

  • 17 + 71453 = 71470
  • 41 + 71429 = 71470
  • 59 + 71411 = 71470
  • 71 + 71399 = 71470
  • 83 + 71387 = 71470
  • 107 + 71363 = 71470
  • 131 + 71339 = 71470
  • 137 + 71333 = 71470

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 71470 first appears in π at position 103,242 of the decimal expansion (the 103,242ordinal-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.
