Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33475140, here are decompositions:

11 + 33475129 = 33475140
29 + 33475111 = 33475140
31 + 33475109 = 33475140
53 + 33475087 = 33475140
59 + 33475081 = 33475140
79 + 33475061 = 33475140
137 + 33475003 = 33475140
163 + 33474977 = 33475140

Showing the first eight; more decompositions exist.
