Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487290, here are decompositions:

13 + 33487277 = 33487290
17 + 33487273 = 33487290
19 + 33487271 = 33487290
29 + 33487261 = 33487290
43 + 33487247 = 33487290
71 + 33487219 = 33487290
97 + 33487193 = 33487290
101 + 33487189 = 33487290

Showing the first eight; more decompositions exist.
