Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33620638, here are decompositions:

11 + 33620627 = 33620638
17 + 33620621 = 33620638
41 + 33620597 = 33620638
47 + 33620591 = 33620638
59 + 33620579 = 33620638
101 + 33620537 = 33620638
131 + 33620507 = 33620638
167 + 33620471 = 33620638

Showing the first eight; more decompositions exist.
