Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33553648, here are decompositions:

41 + 33553607 = 33553648
71 + 33553577 = 33553648
101 + 33553547 = 33553648
131 + 33553517 = 33553648
137 + 33553511 = 33553648
197 + 33553451 = 33553648
269 + 33553379 = 33553648
311 + 33553337 = 33553648

Showing the first eight; more decompositions exist.
