Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622242, here are decompositions:

5 + 31622237 = 31622242
53 + 31622189 = 31622242
59 + 31622183 = 31622242
89 + 31622153 = 31622242
101 + 31622141 = 31622242
263 + 31621979 = 31622242
293 + 31621949 = 31622242
503 + 31621739 = 31622242

Showing the first eight; more decompositions exist.
