Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529234, here are decompositions:

  • 67 + 31529167 = 31529234
  • 127 + 31529107 = 31529234
  • 181 + 31529053 = 31529234
  • 241 + 31528993 = 31529234
  • 421 + 31528813 = 31529234
  • 433 + 31528801 = 31529234
  • 601 + 31528633 = 31529234
  • 613 + 31528621 = 31529234

Showing the first eight; more decompositions exist.
