Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33495680, here are decompositions:

3 + 33495677 = 33495680
37 + 33495643 = 33495680
73 + 33495607 = 33495680
103 + 33495577 = 33495680
193 + 33495487 = 33495680
277 + 33495403 = 33495680
313 + 33495367 = 33495680
367 + 33495313 = 33495680

Showing the first eight; more decompositions exist.
