Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33474780, here are decompositions:

7 + 33474773 = 33474780
13 + 33474767 = 33474780
83 + 33474697 = 33474780
107 + 33474673 = 33474780
113 + 33474667 = 33474780
149 + 33474631 = 33474780
179 + 33474601 = 33474780
211 + 33474569 = 33474780

Showing the first eight; more decompositions exist.
