Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534730, here are decompositions:

  • 61 + 31534669 = 31534730
  • 79 + 31534651 = 31534730
  • 229 + 31534501 = 31534730
  • 307 + 31534423 = 31534730
  • 397 + 31534333 = 31534730
  • 433 + 31534297 = 31534730
  • 499 + 31534231 = 31534730
  • 547 + 31534183 = 31534730

Showing the first eight; more decompositions exist.
