Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680080, here are decompositions:

  • 7 + 8680073 = 8680080
  • 37 + 8680043 = 8680080
  • 43 + 8680037 = 8680080
  • 47 + 8680033 = 8680080
  • 53 + 8680027 = 8680080
  • 89 + 8679991 = 8680080
  • 107 + 8679973 = 8680080
  • 109 + 8679971 = 8680080

Showing the first eight; more decompositions exist.
