Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33485780, here are decompositions:

7 + 33485773 = 33485780
67 + 33485713 = 33485780
79 + 33485701 = 33485780
337 + 33485443 = 33485780
397 + 33485383 = 33485780
439 + 33485341 = 33485780
457 + 33485323 = 33485780
463 + 33485317 = 33485780

Showing the first eight; more decompositions exist.
