Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557784, here are decompositions:

17 + 33557767 = 33557784
31 + 33557753 = 33557784
47 + 33557737 = 33557784
53 + 33557731 = 33557784
83 + 33557701 = 33557784
101 + 33557683 = 33557784
103 + 33557681 = 33557784
157 + 33557627 = 33557784

Showing the first eight; more decompositions exist.
