Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33512872, here are decompositions:

  • 89 + 33512783 = 33512872
  • 149 + 33512723 = 33512872
  • 191 + 33512681 = 33512872
  • 293 + 33512579 = 33512872
  • 401 + 33512471 = 33512872
  • 431 + 33512441 = 33512872
  • 461 + 33512411 = 33512872
  • 563 + 33512309 = 33512872

Showing the first eight; more decompositions exist.
