Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487146, here are decompositions:

29 + 33487117 = 33487146
97 + 33487049 = 33487146
113 + 33487033 = 33487146
149 + 33486997 = 33487146
193 + 33486953 = 33487146
229 + 33486917 = 33487146
283 + 33486863 = 33487146
313 + 33486833 = 33487146

Showing the first eight; more decompositions exist.
