Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513278, here are decompositions:

31 + 33513247 = 33513278
151 + 33513127 = 33513278
181 + 33513097 = 33513278
349 + 33512929 = 33513278
397 + 33512881 = 33513278
439 + 33512839 = 33513278
499 + 33512779 = 33513278
607 + 33512671 = 33513278

Showing the first eight; more decompositions exist.
