Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33615920, here are decompositions:

67 + 33615853 = 33615920
73 + 33615847 = 33615920
97 + 33615823 = 33615920
127 + 33615793 = 33615920
181 + 33615739 = 33615920
271 + 33615649 = 33615920
277 + 33615643 = 33615920
313 + 33615607 = 33615920

Showing the first eight; more decompositions exist.
