Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491490, here are decompositions:

23 + 33491467 = 33491490
29 + 33491461 = 33491490
31 + 33491459 = 33491490
73 + 33491417 = 33491490
103 + 33491387 = 33491490
127 + 33491363 = 33491490
157 + 33491333 = 33491490
223 + 33491267 = 33491490

Showing the first eight; more decompositions exist.
