Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568326, here are decompositions:

17 + 31568309 = 31568326
29 + 31568297 = 31568326
59 + 31568267 = 31568326
197 + 31568129 = 31568326
239 + 31568087 = 31568326
443 + 31567883 = 31568326
467 + 31567859 = 31568326
557 + 31567769 = 31568326

Showing the first eight; more decompositions exist.
