Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33615820, here are decompositions:

23 + 33615797 = 33615820
47 + 33615773 = 33615820
53 + 33615767 = 33615820
59 + 33615761 = 33615820
83 + 33615737 = 33615820
107 + 33615713 = 33615820
113 + 33615707 = 33615820
149 + 33615671 = 33615820

Showing the first eight; more decompositions exist.
