Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747880, here are decompositions:

  • 17 + 8747863 = 8747880
  • 23 + 8747857 = 8747880
  • 61 + 8747819 = 8747880
  • 73 + 8747807 = 8747880
  • 103 + 8747777 = 8747880
  • 137 + 8747743 = 8747880
  • 157 + 8747723 = 8747880
  • 179 + 8747701 = 8747880

Showing the first eight; more decompositions exist.
