Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700144, here are decompositions:

  • 23 + 8700121 = 8700144
  • 31 + 8700113 = 8700144
  • 73 + 8700071 = 8700144
  • 97 + 8700047 = 8700144
  • 107 + 8700037 = 8700144
  • 113 + 8700031 = 8700144
  • 137 + 8700007 = 8700144
  • 151 + 8699993 = 8700144

Showing the first eight; more decompositions exist.
