Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621158, here are decompositions:

127 + 33621031 = 33621158
199 + 33620959 = 33621158
229 + 33620929 = 33621158
349 + 33620809 = 33621158
397 + 33620761 = 33621158
409 + 33620749 = 33621158
499 + 33620659 = 33621158
541 + 33620617 = 33621158

Showing the first eight; more decompositions exist.
