Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538544, here are decompositions:

37 + 33538507 = 33538544
97 + 33538447 = 33538544
103 + 33538441 = 33538544
157 + 33538387 = 33538544
223 + 33538321 = 33538544
241 + 33538303 = 33538544
271 + 33538273 = 33538544
313 + 33538231 = 33538544

Showing the first eight; more decompositions exist.
