Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622862, here are decompositions:

53 + 31622809 = 31622862
59 + 31622803 = 31622862
83 + 31622779 = 31622862
149 + 31622713 = 31622862
163 + 31622699 = 31622862
179 + 31622683 = 31622862
191 + 31622671 = 31622862
199 + 31622663 = 31622862

Showing the first eight; more decompositions exist.
