Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706490, here are decompositions:

  • 11 + 8706479 = 8706490
  • 29 + 8706461 = 8706490
  • 71 + 8706419 = 8706490
  • 83 + 8706407 = 8706490
  • 113 + 8706377 = 8706490
  • 167 + 8706323 = 8706490
  • 239 + 8706251 = 8706490
  • 251 + 8706239 = 8706490

Showing the first eight; more decompositions exist.
