Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527482, here are decompositions:

  • 139 + 31527343 = 31527482
  • 229 + 31527253 = 31527482
  • 271 + 31527211 = 31527482
  • 331 + 31527151 = 31527482
  • 373 + 31527109 = 31527482
  • 541 + 31526941 = 31527482
  • 601 + 31526881 = 31527482
  • 619 + 31526863 = 31527482

Showing the first eight; more decompositions exist.
