Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33486690, here are decompositions:

19 + 33486671 = 33486690
67 + 33486623 = 33486690
79 + 33486611 = 33486690
103 + 33486587 = 33486690
109 + 33486581 = 33486690
113 + 33486577 = 33486690
337 + 33486353 = 33486690
353 + 33486337 = 33486690

Showing the first eight; more decompositions exist.
