Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33600780, here are decompositions:

19 + 33600761 = 33600780
41 + 33600739 = 33600780
43 + 33600737 = 33600780
53 + 33600727 = 33600780
61 + 33600719 = 33600780
67 + 33600713 = 33600780
137 + 33600643 = 33600780
179 + 33600601 = 33600780

Showing the first eight; more decompositions exist.
