Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33620920, here are decompositions:

  • 29 + 33620891 = 33620920
  • 101 + 33620819 = 33620920
  • 107 + 33620813 = 33620920
  • 131 + 33620789 = 33620920
  • 239 + 33620681 = 33620920
  • 293 + 33620627 = 33620920
  • 383 + 33620537 = 33620920
  • 449 + 33620471 = 33620920

Showing the first eight; more decompositions exist.
