Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572992, here are decompositions:

  • 59 + 33572933 = 33572992
  • 71 + 33572921 = 33572992
  • 179 + 33572813 = 33572992
  • 251 + 33572741 = 33572992
  • 293 + 33572699 = 33572992
  • 503 + 33572489 = 33572992
  • 641 + 33572351 = 33572992
  • 653 + 33572339 = 33572992

Showing the first eight; more decompositions exist.
