Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568226, here are decompositions:

5 + 31568221 = 31568226
23 + 31568203 = 31568226
29 + 31568197 = 31568226
47 + 31568179 = 31568226
97 + 31568129 = 31568226
103 + 31568123 = 31568226
139 + 31568087 = 31568226
167 + 31568059 = 31568226

Showing the first eight; more decompositions exist.
