Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487028, here are decompositions:

7 + 33487021 = 33487028
31 + 33486997 = 33487028
181 + 33486847 = 33487028
199 + 33486829 = 33487028
229 + 33486799 = 33487028
277 + 33486751 = 33487028
331 + 33486697 = 33487028
691 + 33486337 = 33487028

Showing the first eight; more decompositions exist.
