Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758218, here are decompositions:

  • 17 + 8758201 = 8758218
  • 19 + 8758199 = 8758218
  • 31 + 8758187 = 8758218
  • 47 + 8758171 = 8758218
  • 61 + 8758157 = 8758218
  • 89 + 8758129 = 8758218
  • 101 + 8758117 = 8758218
  • 137 + 8758081 = 8758218

Showing the first eight; more decompositions exist.
