Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33516728, here are decompositions:

61 + 33516667 = 33516728
97 + 33516631 = 33516728
151 + 33516577 = 33516728
199 + 33516529 = 33516728
331 + 33516397 = 33516728
337 + 33516391 = 33516728
379 + 33516349 = 33516728
409 + 33516319 = 33516728

Showing the first eight; more decompositions exist.
