Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622192, here are decompositions:

3 + 31622189 = 31622192
13 + 31622179 = 31622192
61 + 31622131 = 31622192
73 + 31622119 = 31622192
79 + 31622113 = 31622192
211 + 31621981 = 31622192
229 + 31621963 = 31622192
313 + 31621879 = 31622192

Showing the first eight; more decompositions exist.
