Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33558138, here are decompositions:

37 + 33558101 = 33558138
67 + 33558071 = 33558138
71 + 33558067 = 33558138
79 + 33558059 = 33558138
109 + 33558029 = 33558138
139 + 33557999 = 33558138
151 + 33557987 = 33558138
157 + 33557981 = 33558138

Showing the first eight; more decompositions exist.
