Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33615390, here are decompositions:

31 + 33615359 = 33615390
41 + 33615349 = 33615390
79 + 33615311 = 33615390
101 + 33615289 = 33615390
103 + 33615287 = 33615390
167 + 33615223 = 33615390
239 + 33615151 = 33615390
241 + 33615149 = 33615390

Showing the first eight; more decompositions exist.
