Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730290, here are decompositions:

  • 3 + 8730287 = 8730290
  • 7 + 8730283 = 8730290
  • 61 + 8730229 = 8730290
  • 109 + 8730181 = 8730290
  • 139 + 8730151 = 8730290
  • 199 + 8730091 = 8730290
  • 223 + 8730067 = 8730290
  • 241 + 8730049 = 8730290

Showing the first eight; more decompositions exist.
