Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33573780, here are decompositions:

47 + 33573733 = 33573780
101 + 33573679 = 33573780
113 + 33573667 = 33573780
127 + 33573653 = 33573780
167 + 33573613 = 33573780
179 + 33573601 = 33573780
199 + 33573581 = 33573780
257 + 33573523 = 33573780

Showing the first eight; more decompositions exist.
