Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33577820, here are decompositions:

103 + 33577717 = 33577820
307 + 33577513 = 33577820
439 + 33577381 = 33577820
499 + 33577321 = 33577820
613 + 33577207 = 33577820
643 + 33577177 = 33577820
709 + 33577111 = 33577820
823 + 33576997 = 33577820

Showing the first eight; more decompositions exist.
