Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707838, here are decompositions:

  • 127 + 8707711 = 8707838
  • 151 + 8707687 = 8707838
  • 409 + 8707429 = 8707838
  • 487 + 8707351 = 8707838
  • 619 + 8707219 = 8707838
  • 631 + 8707207 = 8707838
  • 691 + 8707147 = 8707838
  • 859 + 8706979 = 8707838

Showing the first eight; more decompositions exist.
