Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491568, here are decompositions:

7 + 33491561 = 33491568
31 + 33491537 = 33491568
79 + 33491489 = 33491568
101 + 33491467 = 33491568
107 + 33491461 = 33491568
109 + 33491459 = 33491568
127 + 33491441 = 33491568
151 + 33491417 = 33491568

Showing the first eight; more decompositions exist.
