Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33517778, here are decompositions:

31 + 33517747 = 33517778
37 + 33517741 = 33517778
67 + 33517711 = 33517778
97 + 33517681 = 33517778
127 + 33517651 = 33517778
139 + 33517639 = 33517778
241 + 33517537 = 33517778
367 + 33517411 = 33517778

Showing the first eight; more decompositions exist.
