Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487278, here are decompositions:

5 + 33487273 = 33487278
7 + 33487271 = 33487278
17 + 33487261 = 33487278
31 + 33487247 = 33487278
59 + 33487219 = 33487278
89 + 33487189 = 33487278
127 + 33487151 = 33487278
131 + 33487147 = 33487278

Showing the first eight; more decompositions exist.
