Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8675072, here are decompositions:

  • 13 + 8675059 = 8675072
  • 19 + 8675053 = 8675072
  • 61 + 8675011 = 8675072
  • 151 + 8674921 = 8675072
  • 181 + 8674891 = 8675072
  • 313 + 8674759 = 8675072
  • 379 + 8674693 = 8675072
  • 541 + 8674531 = 8675072

Showing the first eight; more decompositions exist.
