Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623838, here are decompositions:

  • 7 + 8623831 = 8623838
  • 31 + 8623807 = 8623838
  • 37 + 8623801 = 8623838
  • 109 + 8623729 = 8623838
  • 151 + 8623687 = 8623838
  • 199 + 8623639 = 8623838
  • 409 + 8623429 = 8623838
  • 499 + 8623339 = 8623838

Showing the first eight; more decompositions exist.
