Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622710, here are decompositions:

11 + 31622699 = 31622710
17 + 31622693 = 31622710
23 + 31622687 = 31622710
47 + 31622663 = 31622710
131 + 31622579 = 31622710
173 + 31622537 = 31622710
191 + 31622519 = 31622710
281 + 31622429 = 31622710

Showing the first eight; more decompositions exist.
