Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33591672, here are decompositions:

5 + 33591667 = 33591672
13 + 33591659 = 33591672
19 + 33591653 = 33591672
31 + 33591641 = 33591672
43 + 33591629 = 33591672
53 + 33591619 = 33591672
139 + 33591533 = 33591672
173 + 33591499 = 33591672

Showing the first eight; more decompositions exist.
