Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33606778, here are decompositions:

71 + 33606707 = 33606778
89 + 33606689 = 33606778
197 + 33606581 = 33606778
251 + 33606527 = 33606778
269 + 33606509 = 33606778
461 + 33606317 = 33606778
479 + 33606299 = 33606778
587 + 33606191 = 33606778

Showing the first eight; more decompositions exist.
