Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487390, here are decompositions:

3 + 33487387 = 33487390
47 + 33487343 = 33487390
71 + 33487319 = 33487390
89 + 33487301 = 33487390
113 + 33487277 = 33487390
197 + 33487193 = 33487390
227 + 33487163 = 33487390
239 + 33487151 = 33487390

Showing the first eight; more decompositions exist.
