Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718290, here are decompositions:

  • 13 + 8718277 = 8718290
  • 19 + 8718271 = 8718290
  • 43 + 8718247 = 8718290
  • 73 + 8718217 = 8718290
  • 127 + 8718163 = 8718290
  • 181 + 8718109 = 8718290
  • 193 + 8718097 = 8718290
  • 199 + 8718091 = 8718290

Showing the first eight; more decompositions exist.
