Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33512800, here are decompositions:

17 + 33512783 = 33512800
47 + 33512753 = 33512800
53 + 33512747 = 33512800
227 + 33512573 = 33512800
263 + 33512537 = 33512800
359 + 33512441 = 33512800
389 + 33512411 = 33512800
491 + 33512309 = 33512800

Showing the first eight; more decompositions exist.
