Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33479780, here are decompositions:

3 + 33479777 = 33479780
7 + 33479773 = 33479780
43 + 33479737 = 33479780
67 + 33479713 = 33479780
79 + 33479701 = 33479780
163 + 33479617 = 33479780
193 + 33479587 = 33479780
331 + 33479449 = 33479780

Showing the first eight; more decompositions exist.
