Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33551240, here are decompositions:

3 + 33551237 = 33551240
31 + 33551209 = 33551240
61 + 33551179 = 33551240
127 + 33551113 = 33551240
199 + 33551041 = 33551240
409 + 33550831 = 33551240
577 + 33550663 = 33551240
607 + 33550633 = 33551240

Showing the first eight; more decompositions exist.
