Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33485642, here are decompositions:

199 + 33485443 = 33485642
331 + 33485311 = 33485642
373 + 33485269 = 33485642
439 + 33485203 = 33485642
499 + 33485143 = 33485642
523 + 33485119 = 33485642
571 + 33485071 = 33485642
643 + 33484999 = 33485642

Showing the first eight; more decompositions exist.
