Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16554, here are decompositions:

  • 7 + 16547 = 16554
  • 61 + 16493 = 16554
  • 67 + 16487 = 16554
  • 73 + 16481 = 16554
  • 101 + 16453 = 16554
  • 103 + 16451 = 16554
  • 107 + 16447 = 16554
  • 127 + 16427 = 16554

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 16554 first appears in π at position 12,360 of the decimal expansion (the 12,360ordinal-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.
