Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672380, here are decompositions:

  • 47 + 8672333 = 8672380
  • 83 + 8672297 = 8672380
  • 107 + 8672273 = 8672380
  • 113 + 8672267 = 8672380
  • 173 + 8672207 = 8672380
  • 179 + 8672201 = 8672380
  • 263 + 8672117 = 8672380
  • 281 + 8672099 = 8672380

Showing the first eight; more decompositions exist.
