Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33515120, here are decompositions:

43 + 33515077 = 33515120
61 + 33515059 = 33515120
151 + 33514969 = 33515120
193 + 33514927 = 33515120
277 + 33514843 = 33515120
523 + 33514597 = 33515120
577 + 33514543 = 33515120
607 + 33514513 = 33515120

Showing the first eight; more decompositions exist.
