Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33494490, here are decompositions:

11 + 33494479 = 33494490
37 + 33494453 = 33494490
59 + 33494431 = 33494490
67 + 33494423 = 33494490
79 + 33494411 = 33494490
83 + 33494407 = 33494490
103 + 33494387 = 33494490
167 + 33494323 = 33494490

Showing the first eight; more decompositions exist.
