Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622202, here are decompositions:

13 + 31622189 = 31622202
19 + 31622183 = 31622202
23 + 31622179 = 31622202
61 + 31622141 = 31622202
71 + 31622131 = 31622202
83 + 31622119 = 31622202
89 + 31622113 = 31622202
223 + 31621979 = 31622202

Showing the first eight; more decompositions exist.
