Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622814, here are decompositions:

5 + 31622809 = 31622814
11 + 31622803 = 31622814
37 + 31622777 = 31622814
71 + 31622743 = 31622814
73 + 31622741 = 31622814
101 + 31622713 = 31622814
127 + 31622687 = 31622814
131 + 31622683 = 31622814

Showing the first eight; more decompositions exist.
