Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530242, here are decompositions:

  • 31 + 31530211 = 31530242
  • 61 + 31530181 = 31530242
  • 181 + 31530061 = 31530242
  • 199 + 31530043 = 31530242
  • 241 + 31530001 = 31530242
  • 571 + 31529671 = 31530242
  • 613 + 31529629 = 31530242
  • 619 + 31529623 = 31530242

Showing the first eight; more decompositions exist.
