Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648390, here are decompositions:

  • 19 + 8648371 = 8648390
  • 43 + 8648347 = 8648390
  • 67 + 8648323 = 8648390
  • 73 + 8648317 = 8648390
  • 139 + 8648251 = 8648390
  • 151 + 8648239 = 8648390
  • 199 + 8648191 = 8648390
  • 211 + 8648179 = 8648390

Showing the first eight; more decompositions exist.
