Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629690, here are decompositions:

  • 11 + 8629679 = 8629690
  • 29 + 8629661 = 8629690
  • 53 + 8629637 = 8629690
  • 107 + 8629583 = 8629690
  • 257 + 8629433 = 8629690
  • 281 + 8629409 = 8629690
  • 347 + 8629343 = 8629690
  • 449 + 8629241 = 8629690

Showing the first eight; more decompositions exist.
