Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491638, here are decompositions:

17 + 33491621 = 33491638
71 + 33491567 = 33491638
101 + 33491537 = 33491638
149 + 33491489 = 33491638
179 + 33491459 = 33491638
197 + 33491441 = 33491638
251 + 33491387 = 33491638
269 + 33491369 = 33491638

Showing the first eight; more decompositions exist.
