Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487442, here are decompositions:

19 + 33487423 = 33487442
181 + 33487261 = 33487442
223 + 33487219 = 33487442
409 + 33487033 = 33487442
421 + 33487021 = 33487442
601 + 33486841 = 33487442
613 + 33486829 = 33487442
643 + 33486799 = 33487442

Showing the first eight; more decompositions exist.
