Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33512420, here are decompositions:

13 + 33512407 = 33512420
37 + 33512383 = 33512420
157 + 33512263 = 33512420
199 + 33512221 = 33512420
229 + 33512191 = 33512420
283 + 33512137 = 33512420
307 + 33512113 = 33512420
367 + 33512053 = 33512420

Showing the first eight; more decompositions exist.
