Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33615720, here are decompositions:

7 + 33615713 = 33615720
13 + 33615707 = 33615720
53 + 33615667 = 33615720
59 + 33615661 = 33615720
71 + 33615649 = 33615720
97 + 33615623 = 33615720
113 + 33615607 = 33615720
137 + 33615583 = 33615720

Showing the first eight; more decompositions exist.
