Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478490, here are decompositions:

13 + 33478477 = 33478490
79 + 33478411 = 33478490
103 + 33478387 = 33478490
307 + 33478183 = 33478490
313 + 33478177 = 33478490
337 + 33478153 = 33478490
379 + 33478111 = 33478490
607 + 33477883 = 33478490

Showing the first eight; more decompositions exist.
