Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33512490, here are decompositions:

13 + 33512477 = 33512490
19 + 33512471 = 33512490
23 + 33512467 = 33512490
59 + 33512431 = 33512490
71 + 33512419 = 33512490
79 + 33512411 = 33512490
83 + 33512407 = 33512490
107 + 33512383 = 33512490

Showing the first eight; more decompositions exist.
