Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1594, here are decompositions:

  • 11 + 1583 = 1594
  • 23 + 1571 = 1594
  • 41 + 1553 = 1594
  • 71 + 1523 = 1594
  • 83 + 1511 = 1594
  • 101 + 1493 = 1594
  • 107 + 1487 = 1594
  • 113 + 1481 = 1594

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 1594 first appears in π at position 10,123 of the decimal expansion (the 10,123ordinal-suffix:rd 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.
