Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33517128, here are decompositions:

11 + 33517117 = 33517128
31 + 33517097 = 33517128
41 + 33517087 = 33517128
67 + 33517061 = 33517128
97 + 33517031 = 33517128
101 + 33517027 = 33517128
107 + 33517021 = 33517128
109 + 33517019 = 33517128

Showing the first eight; more decompositions exist.
