Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33613380, here are decompositions:

13 + 33613367 = 33613380
29 + 33613351 = 33613380
41 + 33613339 = 33613380
103 + 33613277 = 33613380
107 + 33613273 = 33613380
109 + 33613271 = 33613380
137 + 33613243 = 33613380
149 + 33613231 = 33613380

Showing the first eight; more decompositions exist.
