Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33485724, here are decompositions:

7 + 33485717 = 33485724
11 + 33485713 = 33485724
23 + 33485701 = 33485724
37 + 33485687 = 33485724
61 + 33485663 = 33485724
131 + 33485593 = 33485724
157 + 33485567 = 33485724
197 + 33485527 = 33485724

Showing the first eight; more decompositions exist.
