Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487158, here are decompositions:

7 + 33487151 = 33487158
11 + 33487147 = 33487158
37 + 33487121 = 33487158
41 + 33487117 = 33487158
97 + 33487061 = 33487158
109 + 33487049 = 33487158
127 + 33487031 = 33487158
137 + 33487021 = 33487158

Showing the first eight; more decompositions exist.
