Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33486738, here are decompositions:

7 + 33486731 = 33486738
41 + 33486697 = 33486738
67 + 33486671 = 33486738
97 + 33486641 = 33486738
127 + 33486611 = 33486738
151 + 33486587 = 33486738
157 + 33486581 = 33486738
191 + 33486547 = 33486738

Showing the first eight; more decompositions exist.
