Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33512638, here are decompositions:

59 + 33512579 = 33512638
101 + 33512537 = 33512638
167 + 33512471 = 33512638
197 + 33512441 = 33512638
227 + 33512411 = 33512638
359 + 33512279 = 33512638
431 + 33512207 = 33512638
449 + 33512189 = 33512638

Showing the first eight; more decompositions exist.
