Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487042, here are decompositions:

11 + 33487031 = 33487042
89 + 33486953 = 33487042
101 + 33486941 = 33487042
179 + 33486863 = 33487042
293 + 33486749 = 33487042
311 + 33486731 = 33487042
401 + 33486641 = 33487042
419 + 33486623 = 33487042

Showing the first eight; more decompositions exist.
