Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542192, here are decompositions:

  • 29 + 31542163 = 31542192
  • 43 + 31542149 = 31542192
  • 79 + 31542113 = 31542192
  • 89 + 31542103 = 31542192
  • 109 + 31542083 = 31542192
  • 179 + 31542013 = 31542192
  • 181 + 31542011 = 31542192
  • 191 + 31542001 = 31542192

Showing the first eight; more decompositions exist.
