Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478812, here are decompositions:

5 + 33478807 = 33478812
53 + 33478759 = 33478812
61 + 33478751 = 33478812
89 + 33478723 = 33478812
131 + 33478681 = 33478812
163 + 33478649 = 33478812
229 + 33478583 = 33478812
251 + 33478561 = 33478812

Showing the first eight; more decompositions exist.
