Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33486988, here are decompositions:

47 + 33486941 = 33486988
71 + 33486917 = 33486988
131 + 33486857 = 33486988
239 + 33486749 = 33486988
257 + 33486731 = 33486988
317 + 33486671 = 33486988
347 + 33486641 = 33486988
401 + 33486587 = 33486988

Showing the first eight; more decompositions exist.
