Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672990, here are decompositions:

  • 37 + 8672953 = 8672990
  • 43 + 8672947 = 8672990
  • 199 + 8672791 = 8672990
  • 211 + 8672779 = 8672990
  • 223 + 8672767 = 8672990
  • 283 + 8672707 = 8672990
  • 331 + 8672659 = 8672990
  • 349 + 8672641 = 8672990

Showing the first eight; more decompositions exist.
