Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749988, here are decompositions:

  • 7 + 8749981 = 8749988
  • 61 + 8749927 = 8749988
  • 67 + 8749921 = 8749988
  • 97 + 8749891 = 8749988
  • 151 + 8749837 = 8749988
  • 199 + 8749789 = 8749988
  • 337 + 8749651 = 8749988
  • 409 + 8749579 = 8749988

Showing the first eight; more decompositions exist.
