Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459272, here are decompositions:

  • 11 + 31459261 = 31459272
  • 71 + 31459201 = 31459272
  • 73 + 31459199 = 31459272
  • 139 + 31459133 = 31459272
  • 149 + 31459123 = 31459272
  • 179 + 31459093 = 31459272
  • 199 + 31459073 = 31459272
  • 241 + 31459031 = 31459272

Showing the first eight; more decompositions exist.
