Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71630, here are decompositions:

  • 37 + 71593 = 71630
  • 61 + 71569 = 71630
  • 67 + 71563 = 71630
  • 79 + 71551 = 71630
  • 103 + 71527 = 71630
  • 127 + 71503 = 71630
  • 151 + 71479 = 71630
  • 157 + 71473 = 71630

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 71630 first appears in π at position 104,069 of the decimal expansion (the 104,069ordinal-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.
