Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731272, here are decompositions:

  • 23 + 8731249 = 8731272
  • 41 + 8731231 = 8731272
  • 59 + 8731213 = 8731272
  • 61 + 8731211 = 8731272
  • 71 + 8731201 = 8731272
  • 131 + 8731141 = 8731272
  • 163 + 8731109 = 8731272
  • 233 + 8731039 = 8731272

Showing the first eight; more decompositions exist.
