Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33615990, here are decompositions:

7 + 33615983 = 33615990
17 + 33615973 = 33615990
29 + 33615961 = 33615990
43 + 33615947 = 33615990
53 + 33615937 = 33615990
61 + 33615929 = 33615990
97 + 33615893 = 33615990
137 + 33615853 = 33615990

Showing the first eight; more decompositions exist.
