Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530452, here are decompositions:

  • 43 + 31530409 = 31530452
  • 61 + 31530391 = 31530452
  • 103 + 31530349 = 31530452
  • 241 + 31530211 = 31530452
  • 271 + 31530181 = 31530452
  • 409 + 31530043 = 31530452
  • 571 + 31529881 = 31530452
  • 823 + 31529629 = 31530452

Showing the first eight; more decompositions exist.
