Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622770, here are decompositions:

29 + 31622741 = 31622770
41 + 31622729 = 31622770
71 + 31622699 = 31622770
83 + 31622687 = 31622770
107 + 31622663 = 31622770
191 + 31622579 = 31622770
233 + 31622537 = 31622770
251 + 31622519 = 31622770

Showing the first eight; more decompositions exist.
