Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618138, here are decompositions:

19 + 33618119 = 33618138
101 + 33618037 = 33618138
107 + 33618031 = 33618138
109 + 33618029 = 33618138
131 + 33618007 = 33618138
137 + 33618001 = 33618138
139 + 33617999 = 33618138
167 + 33617971 = 33618138

Showing the first eight; more decompositions exist.
