Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621528, here are decompositions:

37 + 33621491 = 33621528
131 + 33621397 = 33621528
139 + 33621389 = 33621528
167 + 33621361 = 33621528
229 + 33621299 = 33621528
277 + 33621251 = 33621528
359 + 33621169 = 33621528
379 + 33621149 = 33621528

Showing the first eight; more decompositions exist.
