Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622772, here are decompositions:

29 + 31622743 = 31622772
31 + 31622741 = 31622772
43 + 31622729 = 31622772
59 + 31622713 = 31622772
73 + 31622699 = 31622772
79 + 31622693 = 31622772
89 + 31622683 = 31622772
101 + 31622671 = 31622772

Showing the first eight; more decompositions exist.
