Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491620, here are decompositions:

17 + 33491603 = 33491620
53 + 33491567 = 33491620
59 + 33491561 = 33491620
83 + 33491537 = 33491620
131 + 33491489 = 33491620
179 + 33491441 = 33491620
233 + 33491387 = 33491620
251 + 33491369 = 33491620

Showing the first eight; more decompositions exist.
