Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33537778, here are decompositions:

11 + 33537767 = 33537778
89 + 33537689 = 33537778
101 + 33537677 = 33537778
179 + 33537599 = 33537778
227 + 33537551 = 33537778
269 + 33537509 = 33537778
359 + 33537419 = 33537778
389 + 33537389 = 33537778

Showing the first eight; more decompositions exist.
