Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557790, here are decompositions:

23 + 33557767 = 33557790
37 + 33557753 = 33557790
41 + 33557749 = 33557790
53 + 33557737 = 33557790
59 + 33557731 = 33557790
61 + 33557729 = 33557790
83 + 33557707 = 33557790
89 + 33557701 = 33557790

Showing the first eight; more decompositions exist.
