Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33506780, here are decompositions:

3 + 33506777 = 33506780
7 + 33506773 = 33506780
157 + 33506623 = 33506780
163 + 33506617 = 33506780
193 + 33506587 = 33506780
199 + 33506581 = 33506780
211 + 33506569 = 33506780
271 + 33506509 = 33506780

Showing the first eight; more decompositions exist.
