Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 98100, here are decompositions:

  • 19 + 98081 = 98100
  • 43 + 98057 = 98100
  • 53 + 98047 = 98100
  • 59 + 98041 = 98100
  • 83 + 98017 = 98100
  • 89 + 98011 = 98100
  • 113 + 97987 = 98100
  • 127 + 97973 = 98100

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 98100 first appears in π at position 28,017 of the decimal expansion (the 28,017ordinal-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.
