Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612870, here are decompositions:

  • 31 + 8612839 = 8612870
  • 103 + 8612767 = 8612870
  • 127 + 8612743 = 8612870
  • 139 + 8612731 = 8612870
  • 157 + 8612713 = 8612870
  • 163 + 8612707 = 8612870
  • 181 + 8612689 = 8612870
  • 199 + 8612671 = 8612870

Showing the first eight; more decompositions exist.
