Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622754, here are decompositions:

11 + 31622743 = 31622754
13 + 31622741 = 31622754
41 + 31622713 = 31622754
61 + 31622693 = 31622754
67 + 31622687 = 31622754
71 + 31622683 = 31622754
83 + 31622671 = 31622754
113 + 31622641 = 31622754

Showing the first eight; more decompositions exist.
