Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622268, here are decompositions:

11 + 31622257 = 31622268
31 + 31622237 = 31622268
61 + 31622207 = 31622268
79 + 31622189 = 31622268
89 + 31622179 = 31622268
101 + 31622167 = 31622268
127 + 31622141 = 31622268
137 + 31622131 = 31622268

Showing the first eight; more decompositions exist.
