Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568464, here are decompositions:

41 + 31568423 = 31568464
47 + 31568417 = 31568464
71 + 31568393 = 31568464
107 + 31568357 = 31568464
131 + 31568333 = 31568464
167 + 31568297 = 31568464
197 + 31568267 = 31568464
443 + 31568021 = 31568464

Showing the first eight; more decompositions exist.
