Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671896, here are decompositions:

  • 59 + 8671837 = 8671896
  • 127 + 8671769 = 8671896
  • 157 + 8671739 = 8671896
  • 199 + 8671697 = 8671896
  • 227 + 8671669 = 8671896
  • 257 + 8671639 = 8671896
  • 263 + 8671633 = 8671896
  • 307 + 8671589 = 8671896

Showing the first eight; more decompositions exist.
