Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568134, here are decompositions:

5 + 31568129 = 31568134
11 + 31568123 = 31568134
47 + 31568087 = 31568134
107 + 31568027 = 31568134
113 + 31568021 = 31568134
173 + 31567961 = 31568134
251 + 31567883 = 31568134
461 + 31567673 = 31568134

Showing the first eight; more decompositions exist.
