Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33613780, here are decompositions:

17 + 33613763 = 33613780
23 + 33613757 = 33613780
29 + 33613751 = 33613780
41 + 33613739 = 33613780
281 + 33613499 = 33613780
311 + 33613469 = 33613780
503 + 33613277 = 33613780
509 + 33613271 = 33613780

Showing the first eight; more decompositions exist.
