Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33508942, here are decompositions:

23 + 33508919 = 33508942
41 + 33508901 = 33508942
83 + 33508859 = 33508942
113 + 33508829 = 33508942
281 + 33508661 = 33508942
359 + 33508583 = 33508942
443 + 33508499 = 33508942
479 + 33508463 = 33508942

Showing the first eight; more decompositions exist.
