Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33512528, here are decompositions:

61 + 33512467 = 33512528
97 + 33512431 = 33512528
109 + 33512419 = 33512528
229 + 33512299 = 33512528
307 + 33512221 = 33512528
337 + 33512191 = 33512528
739 + 33511789 = 33512528
811 + 33511717 = 33512528

Showing the first eight; more decompositions exist.
