Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33506228, here are decompositions:

97 + 33506131 = 33506228
181 + 33506047 = 33506228
277 + 33505951 = 33506228
439 + 33505789 = 33506228
607 + 33505621 = 33506228
661 + 33505567 = 33506228
709 + 33505519 = 33506228
787 + 33505441 = 33506228

Showing the first eight; more decompositions exist.
