Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33517818, here are decompositions:

7 + 33517811 = 33517818
71 + 33517747 = 33517818
107 + 33517711 = 33517818
137 + 33517681 = 33517818
167 + 33517651 = 33517818
179 + 33517639 = 33517818
199 + 33517619 = 33517818
281 + 33517537 = 33517818

Showing the first eight; more decompositions exist.
