Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727880, here are decompositions:

  • 23 + 8727857 = 8727880
  • 71 + 8727809 = 8727880
  • 89 + 8727791 = 8727880
  • 101 + 8727779 = 8727880
  • 107 + 8727773 = 8727880
  • 113 + 8727767 = 8727880
  • 149 + 8727731 = 8727880
  • 179 + 8727701 = 8727880

Showing the first eight; more decompositions exist.
