Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33497818, here are decompositions:

41 + 33497777 = 33497818
71 + 33497747 = 33497818
131 + 33497687 = 33497818
239 + 33497579 = 33497818
251 + 33497567 = 33497818
257 + 33497561 = 33497818
269 + 33497549 = 33497818
311 + 33497507 = 33497818

Showing the first eight; more decompositions exist.
