Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33620780, here are decompositions:

13 + 33620767 = 33620780
19 + 33620761 = 33620780
31 + 33620749 = 33620780
73 + 33620707 = 33620780
157 + 33620623 = 33620780
163 + 33620617 = 33620780
307 + 33620473 = 33620780
313 + 33620467 = 33620780

Showing the first eight; more decompositions exist.
