Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33517878, here are decompositions:

5 + 33517873 = 33517878
7 + 33517871 = 33517878
29 + 33517849 = 33517878
67 + 33517811 = 33517878
131 + 33517747 = 33517878
137 + 33517741 = 33517878
167 + 33517711 = 33517878
181 + 33517697 = 33517878

Showing the first eight; more decompositions exist.
