Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33615900, here are decompositions:

7 + 33615893 = 33615900
47 + 33615853 = 33615900
53 + 33615847 = 33615900
103 + 33615797 = 33615900
107 + 33615793 = 33615900
127 + 33615773 = 33615900
139 + 33615761 = 33615900
163 + 33615737 = 33615900

Showing the first eight; more decompositions exist.
