Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33512818, here are decompositions:

11 + 33512807 = 33512818
71 + 33512747 = 33512818
137 + 33512681 = 33512818
239 + 33512579 = 33512818
281 + 33512537 = 33512818
347 + 33512471 = 33512818
509 + 33512309 = 33512818
587 + 33512231 = 33512818

Showing the first eight; more decompositions exist.
