Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628984, here are decompositions:

  • 11 + 8628973 = 8628984
  • 17 + 8628967 = 8628984
  • 47 + 8628937 = 8628984
  • 61 + 8628923 = 8628984
  • 71 + 8628913 = 8628984
  • 101 + 8628883 = 8628984
  • 127 + 8628857 = 8628984
  • 137 + 8628847 = 8628984

Showing the first eight; more decompositions exist.
