Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33537868, here are decompositions:

5 + 33537863 = 33537868
11 + 33537857 = 33537868
29 + 33537839 = 33537868
59 + 33537809 = 33537868
71 + 33537797 = 33537868
101 + 33537767 = 33537868
167 + 33537701 = 33537868
179 + 33537689 = 33537868

Showing the first eight; more decompositions exist.
