Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622098, here are decompositions:

17 + 31622081 = 31622098
149 + 31621949 = 31622098
197 + 31621901 = 31622098
251 + 31621847 = 31622098
359 + 31621739 = 31622098
419 + 31621679 = 31622098
461 + 31621637 = 31622098
467 + 31621631 = 31622098

Showing the first eight; more decompositions exist.
