Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670940, here are decompositions:

  • 53 + 8670887 = 8670940
  • 71 + 8670869 = 8670940
  • 149 + 8670791 = 8670940
  • 167 + 8670773 = 8670940
  • 197 + 8670743 = 8670940
  • 227 + 8670713 = 8670940
  • 389 + 8670551 = 8670940
  • 431 + 8670509 = 8670940

Showing the first eight; more decompositions exist.
