Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33615220, here are decompositions:

71 + 33615149 = 33615220
101 + 33615119 = 33615220
251 + 33614969 = 33615220
257 + 33614963 = 33615220
269 + 33614951 = 33615220
281 + 33614939 = 33615220
311 + 33614909 = 33615220
521 + 33614699 = 33615220

Showing the first eight; more decompositions exist.
