Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33488490, here are decompositions:

11 + 33488479 = 33488490
19 + 33488471 = 33488490
23 + 33488467 = 33488490
29 + 33488461 = 33488490
41 + 33488449 = 33488490
83 + 33488407 = 33488490
109 + 33488381 = 33488490
137 + 33488353 = 33488490

Showing the first eight; more decompositions exist.
