Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33578780, here are decompositions:

7 + 33578773 = 33578780
13 + 33578767 = 33578780
19 + 33578761 = 33578780
31 + 33578749 = 33578780
73 + 33578707 = 33578780
97 + 33578683 = 33578780
139 + 33578641 = 33578780
163 + 33578617 = 33578780

Showing the first eight; more decompositions exist.
