Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677860, here are decompositions:

  • 13 + 8677847 = 8677860
  • 19 + 8677841 = 8677860
  • 31 + 8677829 = 8677860
  • 89 + 8677771 = 8677860
  • 97 + 8677763 = 8677860
  • 101 + 8677759 = 8677860
  • 137 + 8677723 = 8677860
  • 179 + 8677681 = 8677860

Showing the first eight; more decompositions exist.
