Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612342, here are decompositions:

  • 29 + 31612313 = 31612342
  • 101 + 31612241 = 31612342
  • 191 + 31612151 = 31612342
  • 233 + 31612109 = 31612342
  • 263 + 31612079 = 31612342
  • 401 + 31611941 = 31612342
  • 431 + 31611911 = 31612342
  • 449 + 31611893 = 31612342

Showing the first eight; more decompositions exist.
