Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529378, here are decompositions:

  • 19 + 31529359 = 31529378
  • 31 + 31529347 = 31529378
  • 109 + 31529269 = 31529378
  • 211 + 31529167 = 31529378
  • 229 + 31529149 = 31529378
  • 271 + 31529107 = 31529378
  • 409 + 31528969 = 31529378
  • 547 + 31528831 = 31529378

Showing the first eight; more decompositions exist.
