Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629990, here are decompositions:

  • 29 + 8629961 = 8629990
  • 41 + 8629949 = 8629990
  • 101 + 8629889 = 8629990
  • 107 + 8629883 = 8629990
  • 167 + 8629823 = 8629990
  • 227 + 8629763 = 8629990
  • 251 + 8629739 = 8629990
  • 311 + 8629679 = 8629990

Showing the first eight; more decompositions exist.
