Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622748, here are decompositions:

  • 5 + 31622743 = 31622748
  • 7 + 31622741 = 31622748
  • 19 + 31622729 = 31622748
  • 61 + 31622687 = 31622748
  • 107 + 31622641 = 31622748
  • 149 + 31622599 = 31622748
  • 211 + 31622537 = 31622748
  • 229 + 31622519 = 31622748

Showing the first eight; more decompositions exist.
