Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568196, here are decompositions:

17 + 31568179 = 31568196
67 + 31568129 = 31568196
73 + 31568123 = 31568196
89 + 31568107 = 31568196
109 + 31568087 = 31568196
113 + 31568083 = 31568196
137 + 31568059 = 31568196
197 + 31567999 = 31568196

Showing the first eight; more decompositions exist.
