Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33620900, here are decompositions:

  • 43 + 33620857 = 33620900
  • 97 + 33620803 = 33620900
  • 139 + 33620761 = 33620900
  • 151 + 33620749 = 33620900
  • 193 + 33620707 = 33620900
  • 211 + 33620689 = 33620900
  • 241 + 33620659 = 33620900
  • 277 + 33620623 = 33620900

Showing the first eight; more decompositions exist.
