Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622082, here are decompositions:

101 + 31621981 = 31622082
103 + 31621979 = 31622082
181 + 31621901 = 31622082
251 + 31621831 = 31622082
379 + 31621703 = 31622082
389 + 31621693 = 31622082
409 + 31621673 = 31622082
421 + 31621661 = 31622082

Showing the first eight; more decompositions exist.
