Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622320, here are decompositions:

47 + 31622273 = 31622320
83 + 31622237 = 31622320
113 + 31622207 = 31622320
131 + 31622189 = 31622320
137 + 31622183 = 31622320
167 + 31622153 = 31622320
173 + 31622147 = 31622320
179 + 31622141 = 31622320

Showing the first eight; more decompositions exist.
