Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33615388, here are decompositions:

29 + 33615359 = 33615388
89 + 33615299 = 33615388
101 + 33615287 = 33615388
167 + 33615221 = 33615388
239 + 33615149 = 33615388
269 + 33615119 = 33615388
419 + 33614969 = 33615388
449 + 33614939 = 33615388

Showing the first eight; more decompositions exist.
