Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622248, here are decompositions:

11 + 31622237 = 31622248
41 + 31622207 = 31622248
59 + 31622189 = 31622248
101 + 31622147 = 31622248
107 + 31622141 = 31622248
167 + 31622081 = 31622248
269 + 31621979 = 31622248
347 + 31621901 = 31622248

Showing the first eight; more decompositions exist.
