Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665980, here are decompositions:

  • 7 + 8665973 = 8665980
  • 13 + 8665967 = 8665980
  • 31 + 8665949 = 8665980
  • 41 + 8665939 = 8665980
  • 47 + 8665933 = 8665980
  • 67 + 8665913 = 8665980
  • 83 + 8665897 = 8665980
  • 107 + 8665873 = 8665980

Showing the first eight; more decompositions exist.
