Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528862, here are decompositions:

  • 19 + 31528843 = 31528862
  • 31 + 31528831 = 31528862
  • 61 + 31528801 = 31528862
  • 139 + 31528723 = 31528862
  • 193 + 31528669 = 31528862
  • 229 + 31528633 = 31528862
  • 241 + 31528621 = 31528862
  • 283 + 31528579 = 31528862

Showing the first eight; more decompositions exist.
