Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622776, here are decompositions:

47 + 31622729 = 31622776
83 + 31622693 = 31622776
89 + 31622687 = 31622776
113 + 31622663 = 31622776
197 + 31622579 = 31622776
239 + 31622537 = 31622776
257 + 31622519 = 31622776
347 + 31622429 = 31622776

Showing the first eight; more decompositions exist.
