Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33553578, here are decompositions:

29 + 33553549 = 33553578
31 + 33553547 = 33553578
41 + 33553537 = 33553578
59 + 33553519 = 33553578
61 + 33553517 = 33553578
67 + 33553511 = 33553578
89 + 33553489 = 33553578
127 + 33553451 = 33553578

Showing the first eight; more decompositions exist.
