Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33506978, here are decompositions:

31 + 33506947 = 33506978
157 + 33506821 = 33506978
181 + 33506797 = 33506978
397 + 33506581 = 33506978
409 + 33506569 = 33506978
457 + 33506521 = 33506978
499 + 33506479 = 33506978
577 + 33506401 = 33506978

Showing the first eight; more decompositions exist.
