Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33615428, here are decompositions:

79 + 33615349 = 33615428
139 + 33615289 = 33615428
157 + 33615271 = 33615428
199 + 33615229 = 33615428
277 + 33615151 = 33615428
349 + 33615079 = 33615428
367 + 33615061 = 33615428
409 + 33615019 = 33615428

Showing the first eight; more decompositions exist.
