Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1576, here are decompositions:

  • 5 + 1571 = 1576
  • 17 + 1559 = 1576
  • 23 + 1553 = 1576
  • 53 + 1523 = 1576
  • 83 + 1493 = 1576
  • 89 + 1487 = 1576
  • 137 + 1439 = 1576
  • 149 + 1427 = 1576

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 1576 first appears in π at position 7,345 of the decimal expansion (the 7,345ordinal-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.
