Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491688, here are decompositions:

7 + 33491681 = 33491688
17 + 33491671 = 33491688
47 + 33491641 = 33491688
67 + 33491621 = 33491688
89 + 33491599 = 33491688
127 + 33491561 = 33491688
151 + 33491537 = 33491688
199 + 33491489 = 33491688

Showing the first eight; more decompositions exist.
