Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33490812, here are decompositions:

11 + 33490801 = 33490812
31 + 33490781 = 33490812
233 + 33490579 = 33490812
239 + 33490573 = 33490812
283 + 33490529 = 33490812
293 + 33490519 = 33490812
349 + 33490463 = 33490812
359 + 33490453 = 33490812

Showing the first eight; more decompositions exist.
