Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724270, here are decompositions:

  • 7 + 8724263 = 8724270
  • 11 + 8724259 = 8724270
  • 17 + 8724253 = 8724270
  • 29 + 8724241 = 8724270
  • 47 + 8724223 = 8724270
  • 89 + 8724181 = 8724270
  • 101 + 8724169 = 8724270
  • 109 + 8724161 = 8724270

Showing the first eight; more decompositions exist.
