Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506332, here are decompositions:

  • 61 + 31506271 = 31506332
  • 139 + 31506193 = 31506332
  • 229 + 31506103 = 31506332
  • 241 + 31506091 = 31506332
  • 271 + 31506061 = 31506332
  • 349 + 31505983 = 31506332
  • 373 + 31505959 = 31506332
  • 409 + 31505923 = 31506332

Showing the first eight; more decompositions exist.
