Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542176, here are decompositions:

  • 13 + 31542163 = 31542176
  • 73 + 31542103 = 31542176
  • 109 + 31542067 = 31542176
  • 139 + 31542037 = 31542176
  • 163 + 31542013 = 31542176
  • 199 + 31541977 = 31542176
  • 277 + 31541899 = 31542176
  • 283 + 31541893 = 31542176

Showing the first eight; more decompositions exist.
