Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622802, here are decompositions:

23 + 31622779 = 31622802
59 + 31622743 = 31622802
61 + 31622741 = 31622802
73 + 31622729 = 31622802
89 + 31622713 = 31622802
103 + 31622699 = 31622802
109 + 31622693 = 31622802
131 + 31622671 = 31622802

Showing the first eight; more decompositions exist.
