Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18462, here are decompositions:

  • 5 + 18457 = 18462
  • 11 + 18451 = 18462
  • 19 + 18443 = 18462
  • 23 + 18439 = 18462
  • 29 + 18433 = 18462
  • 61 + 18401 = 18462
  • 83 + 18379 = 18462
  • 109 + 18353 = 18462

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 18462 first appears in π at position 102,293 of the decimal expansion (the 102,293ordinal-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.
