Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639270, here are decompositions:

  • 7 + 8639263 = 8639270
  • 19 + 8639251 = 8639270
  • 43 + 8639227 = 8639270
  • 109 + 8639161 = 8639270
  • 127 + 8639143 = 8639270
  • 139 + 8639131 = 8639270
  • 151 + 8639119 = 8639270
  • 163 + 8639107 = 8639270

Showing the first eight; more decompositions exist.
