Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622712, here are decompositions:

13 + 31622699 = 31622712
19 + 31622693 = 31622712
29 + 31622683 = 31622712
41 + 31622671 = 31622712
71 + 31622641 = 31622712
83 + 31622629 = 31622712
113 + 31622599 = 31622712
193 + 31622519 = 31622712

Showing the first eight; more decompositions exist.
