Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1738, here are decompositions:

  • 5 + 1733 = 1738
  • 17 + 1721 = 1738
  • 29 + 1709 = 1738
  • 41 + 1697 = 1738
  • 71 + 1667 = 1738
  • 101 + 1637 = 1738
  • 131 + 1607 = 1738
  • 137 + 1601 = 1738

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 1738 first appears in π at position 428 of the decimal expansion (the 428ordinal-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.
