Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622908, here are decompositions:

71 + 31622837 = 31622908
131 + 31622777 = 31622908
167 + 31622741 = 31622908
179 + 31622729 = 31622908
389 + 31622519 = 31622908
479 + 31622429 = 31622908
701 + 31622207 = 31622908
719 + 31622189 = 31622908

Showing the first eight; more decompositions exist.
