Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623646, here are decompositions:

  • 7 + 8623639 = 8623646
  • 43 + 8623603 = 8623646
  • 67 + 8623579 = 8623646
  • 127 + 8623519 = 8623646
  • 223 + 8623423 = 8623646
  • 307 + 8623339 = 8623646
  • 397 + 8623249 = 8623646
  • 433 + 8623213 = 8623646

Showing the first eight; more decompositions exist.
