Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491320, here are decompositions:

17 + 33491303 = 33491320
53 + 33491267 = 33491320
59 + 33491261 = 33491320
167 + 33491153 = 33491320
173 + 33491147 = 33491320
179 + 33491141 = 33491320
257 + 33491063 = 33491320
263 + 33491057 = 33491320

Showing the first eight; more decompositions exist.
