Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33615978, here are decompositions:

5 + 33615973 = 33615978
17 + 33615961 = 33615978
31 + 33615947 = 33615978
41 + 33615937 = 33615978
131 + 33615847 = 33615978
181 + 33615797 = 33615978
211 + 33615767 = 33615978
239 + 33615739 = 33615978

Showing the first eight; more decompositions exist.
