Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568334, here are decompositions:

23 + 31568311 = 31568334
37 + 31568297 = 31568334
47 + 31568287 = 31568334
53 + 31568281 = 31568334
67 + 31568267 = 31568334
107 + 31568227 = 31568334
113 + 31568221 = 31568334
131 + 31568203 = 31568334

Showing the first eight; more decompositions exist.
