Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700156, here are decompositions:

  • 43 + 8700113 = 8700156
  • 97 + 8700059 = 8700156
  • 109 + 8700047 = 8700156
  • 137 + 8700019 = 8700156
  • 149 + 8700007 = 8700156
  • 163 + 8699993 = 8700156
  • 197 + 8699959 = 8700156
  • 233 + 8699923 = 8700156

Showing the first eight; more decompositions exist.
