Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33518490, here are decompositions:

37 + 33518453 = 33518490
41 + 33518449 = 33518490
53 + 33518437 = 33518490
73 + 33518417 = 33518490
97 + 33518393 = 33518490
101 + 33518389 = 33518490
139 + 33518351 = 33518490
157 + 33518333 = 33518490

Showing the first eight; more decompositions exist.
