Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487170, here are decompositions:

7 + 33487163 = 33487170
19 + 33487151 = 33487170
23 + 33487147 = 33487170
53 + 33487117 = 33487170
89 + 33487081 = 33487170
109 + 33487061 = 33487170
137 + 33487033 = 33487170
139 + 33487031 = 33487170

Showing the first eight; more decompositions exist.
