Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16606, here are decompositions:

  • 3 + 16603 = 16606
  • 53 + 16553 = 16606
  • 59 + 16547 = 16606
  • 113 + 16493 = 16606
  • 173 + 16433 = 16606
  • 179 + 16427 = 16606
  • 257 + 16349 = 16606
  • 353 + 16253 = 16606

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 16606 first appears in π at position 120,978 of the decimal expansion (the 120,978ordinal-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.
