Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33503578, here are decompositions:

5 + 33503573 = 33503578
149 + 33503429 = 33503578
167 + 33503411 = 33503578
179 + 33503399 = 33503578
401 + 33503177 = 33503578
491 + 33503087 = 33503578
509 + 33503069 = 33503578
557 + 33503021 = 33503578

Showing the first eight; more decompositions exist.
