Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478550, here are decompositions:

19 + 33478531 = 33478550
73 + 33478477 = 33478550
139 + 33478411 = 33478550
163 + 33478387 = 33478550
277 + 33478273 = 33478550
349 + 33478201 = 33478550
367 + 33478183 = 33478550
373 + 33478177 = 33478550

Showing the first eight; more decompositions exist.
