Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33544638, here are decompositions:

7 + 33544631 = 33544638
41 + 33544597 = 33544638
59 + 33544579 = 33544638
97 + 33544541 = 33544638
137 + 33544501 = 33544638
151 + 33544487 = 33544638
181 + 33544457 = 33544638
241 + 33544397 = 33544638

Showing the first eight; more decompositions exist.
