Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8675172, here are decompositions:

  • 59 + 8675113 = 8675172
  • 61 + 8675111 = 8675172
  • 73 + 8675099 = 8675172
  • 113 + 8675059 = 8675172
  • 139 + 8675033 = 8675172
  • 151 + 8675021 = 8675172
  • 211 + 8674961 = 8675172
  • 251 + 8674921 = 8675172

Showing the first eight; more decompositions exist.
