Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542204, here are decompositions:

  • 7 + 31542197 = 31542204
  • 41 + 31542163 = 31542204
  • 101 + 31542103 = 31542204
  • 137 + 31542067 = 31542204
  • 167 + 31542037 = 31542204
  • 173 + 31542031 = 31542204
  • 181 + 31542023 = 31542204
  • 191 + 31542013 = 31542204

Showing the first eight; more decompositions exist.
