Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677920, here are decompositions:

  • 29 + 8677891 = 8677920
  • 37 + 8677883 = 8677920
  • 73 + 8677847 = 8677920
  • 79 + 8677841 = 8677920
  • 149 + 8677771 = 8677920
  • 157 + 8677763 = 8677920
  • 193 + 8677727 = 8677920
  • 197 + 8677723 = 8677920

Showing the first eight; more decompositions exist.
