Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618042, here are decompositions:

5 + 33618037 = 33618042
11 + 33618031 = 33618042
13 + 33618029 = 33618042
41 + 33618001 = 33618042
43 + 33617999 = 33618042
71 + 33617971 = 33618042
79 + 33617963 = 33618042
109 + 33617933 = 33618042

Showing the first eight; more decompositions exist.
