Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478784, here are decompositions:

61 + 33478723 = 33478784
103 + 33478681 = 33478784
223 + 33478561 = 33478784
307 + 33478477 = 33478784
373 + 33478411 = 33478784
397 + 33478387 = 33478784
601 + 33478183 = 33478784
607 + 33478177 = 33478784

Showing the first eight; more decompositions exist.
