Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33553530, here are decompositions:

11 + 33553519 = 33553530
13 + 33553517 = 33553530
19 + 33553511 = 33553530
41 + 33553489 = 33553530
67 + 33553463 = 33553530
79 + 33553451 = 33553530
113 + 33553417 = 33553530
151 + 33553379 = 33553530

Showing the first eight; more decompositions exist.
