Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622038, here are decompositions:

59 + 31621979 = 31622038
89 + 31621949 = 31622038
137 + 31621901 = 31622038
191 + 31621847 = 31622038
359 + 31621679 = 31622038
401 + 31621637 = 31622038
479 + 31621559 = 31622038
521 + 31621517 = 31622038

Showing the first eight; more decompositions exist.
