Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561578, here are decompositions:

7 + 33561571 = 33561578
19 + 33561559 = 33561578
109 + 33561469 = 33561578
199 + 33561379 = 33561578
307 + 33561271 = 33561578
397 + 33561181 = 33561578
409 + 33561169 = 33561578
439 + 33561139 = 33561578

Showing the first eight; more decompositions exist.
