Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622356, here are decompositions:

83 + 31622273 = 31622356
149 + 31622207 = 31622356
167 + 31622189 = 31622356
173 + 31622183 = 31622356
509 + 31621847 = 31622356
617 + 31621739 = 31622356
653 + 31621703 = 31622356
677 + 31621679 = 31622356

Showing the first eight; more decompositions exist.
