Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538780, here are decompositions:

17 + 33538763 = 33538780
59 + 33538721 = 33538780
71 + 33538709 = 33538780
101 + 33538679 = 33538780
131 + 33538649 = 33538780
137 + 33538643 = 33538780
179 + 33538601 = 33538780
257 + 33538523 = 33538780

Showing the first eight; more decompositions exist.
