Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33512438, here are decompositions:

7 + 33512431 = 33512438
19 + 33512419 = 33512438
31 + 33512407 = 33512438
139 + 33512299 = 33512438
499 + 33511939 = 33512438
577 + 33511861 = 33512438
709 + 33511729 = 33512438
769 + 33511669 = 33512438

Showing the first eight; more decompositions exist.
