Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33517812, here are decompositions:

19 + 33517793 = 33517812
59 + 33517753 = 33517812
71 + 33517741 = 33517812
101 + 33517711 = 33517812
131 + 33517681 = 33517812
173 + 33517639 = 33517812
179 + 33517633 = 33517812
193 + 33517619 = 33517812

Showing the first eight; more decompositions exist.
