Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487018, here are decompositions:

101 + 33486917 = 33487018
251 + 33486767 = 33487018
269 + 33486749 = 33487018
347 + 33486671 = 33487018
431 + 33486587 = 33487018
647 + 33486371 = 33487018
821 + 33486197 = 33487018
827 + 33486191 = 33487018

Showing the first eight; more decompositions exist.
