Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622302, here are decompositions:

29 + 31622273 = 31622302
113 + 31622189 = 31622302
149 + 31622153 = 31622302
353 + 31621949 = 31622302
401 + 31621901 = 31622302
563 + 31621739 = 31622302
599 + 31621703 = 31622302
641 + 31621661 = 31622302

Showing the first eight; more decompositions exist.
