Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681486, here are decompositions:

  • 3 + 8681483 = 8681486
  • 13 + 8681473 = 8681486
  • 19 + 8681467 = 8681486
  • 109 + 8681377 = 8681486
  • 127 + 8681359 = 8681486
  • 199 + 8681287 = 8681486
  • 223 + 8681263 = 8681486
  • 397 + 8681089 = 8681486

Showing the first eight; more decompositions exist.
