Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33490780, here are decompositions:

3 + 33490777 = 33490780
17 + 33490763 = 33490780
173 + 33490607 = 33490780
233 + 33490547 = 33490780
251 + 33490529 = 33490780
317 + 33490463 = 33490780
383 + 33490397 = 33490780
419 + 33490361 = 33490780

Showing the first eight; more decompositions exist.
