Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33486642, here are decompositions:

19 + 33486623 = 33486642
31 + 33486611 = 33486642
61 + 33486581 = 33486642
173 + 33486469 = 33486642
239 + 33486403 = 33486642
251 + 33486391 = 33486642
271 + 33486371 = 33486642
281 + 33486361 = 33486642

Showing the first eight; more decompositions exist.
