Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33539128, here are decompositions:

149 + 33538979 = 33539128
179 + 33538949 = 33539128
191 + 33538937 = 33539128
269 + 33538859 = 33539128
419 + 33538709 = 33539128
449 + 33538679 = 33539128
479 + 33538649 = 33539128
509 + 33538619 = 33539128

Showing the first eight; more decompositions exist.
