Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672980, here are decompositions:

  • 11 + 8672969 = 8672980
  • 47 + 8672933 = 8672980
  • 53 + 8672927 = 8672980
  • 83 + 8672897 = 8672980
  • 89 + 8672891 = 8672980
  • 149 + 8672831 = 8672980
  • 179 + 8672801 = 8672980
  • 191 + 8672789 = 8672980

Showing the first eight; more decompositions exist.
