Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33615980, here are decompositions:

7 + 33615973 = 33615980
19 + 33615961 = 33615980
43 + 33615937 = 33615980
127 + 33615853 = 33615980
157 + 33615823 = 33615980
241 + 33615739 = 33615980
313 + 33615667 = 33615980
331 + 33615649 = 33615980

Showing the first eight; more decompositions exist.
