Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33615580, here are decompositions:

23 + 33615557 = 33615580
41 + 33615539 = 33615580
59 + 33615521 = 33615580
101 + 33615479 = 33615580
107 + 33615473 = 33615580
113 + 33615467 = 33615580
179 + 33615401 = 33615580
269 + 33615311 = 33615580

Showing the first eight; more decompositions exist.
