Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33553538, here are decompositions:

19 + 33553519 = 33553538
181 + 33553357 = 33553538
211 + 33553327 = 33553538
367 + 33553171 = 33553538
397 + 33553141 = 33553538
709 + 33552829 = 33553538
727 + 33552811 = 33553538
751 + 33552787 = 33553538

Showing the first eight; more decompositions exist.
