Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542342, here are decompositions:

  • 19 + 31542323 = 31542342
  • 61 + 31542281 = 31542342
  • 109 + 31542233 = 31542342
  • 113 + 31542229 = 31542342
  • 179 + 31542163 = 31542342
  • 193 + 31542149 = 31542342
  • 229 + 31542113 = 31542342
  • 239 + 31542103 = 31542342

Showing the first eight; more decompositions exist.
