Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581550, here are decompositions:

29 + 33581521 = 33581550
59 + 33581491 = 33581550
109 + 33581441 = 33581550
113 + 33581437 = 33581550
137 + 33581413 = 33581550
139 + 33581411 = 33581550
157 + 33581393 = 33581550
199 + 33581351 = 33581550

Showing the first eight; more decompositions exist.
