Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622368, here are decompositions:

131 + 31622237 = 31622368
179 + 31622189 = 31622368
227 + 31622141 = 31622368
389 + 31621979 = 31622368
419 + 31621949 = 31622368
467 + 31621901 = 31622368
521 + 31621847 = 31622368
809 + 31621559 = 31622368

Showing the first eight; more decompositions exist.
