Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99018, here are decompositions:

  • 5 + 99013 = 99018
  • 19 + 98999 = 99018
  • 37 + 98981 = 99018
  • 71 + 98947 = 99018
  • 79 + 98939 = 99018
  • 89 + 98929 = 99018
  • 107 + 98911 = 99018
  • 109 + 98909 = 99018

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 99018 first appears in π at position 30,254 of the decimal expansion (the 30,254ordinal-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.
