Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622186, here are decompositions:

3 + 31622183 = 31622186
7 + 31622179 = 31622186
19 + 31622167 = 31622186
67 + 31622119 = 31622186
73 + 31622113 = 31622186
139 + 31622047 = 31622186
223 + 31621963 = 31622186
229 + 31621957 = 31622186

Showing the first eight; more decompositions exist.
