Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528802, here are decompositions:

  • 61 + 31528741 = 31528802
  • 73 + 31528729 = 31528802
  • 79 + 31528723 = 31528802
  • 181 + 31528621 = 31528802
  • 223 + 31528579 = 31528802
  • 229 + 31528573 = 31528802
  • 271 + 31528531 = 31528802
  • 439 + 31528363 = 31528802

Showing the first eight; more decompositions exist.
