Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691386, here are decompositions:

  • 3 + 8691383 = 8691386
  • 13 + 8691373 = 8691386
  • 19 + 8691367 = 8691386
  • 73 + 8691313 = 8691386
  • 139 + 8691247 = 8691386
  • 157 + 8691229 = 8691386
  • 163 + 8691223 = 8691386
  • 199 + 8691187 = 8691386

Showing the first eight; more decompositions exist.
