Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623164, here are decompositions:

43 + 31623121 = 31623164
103 + 31623061 = 31623164
241 + 31622923 = 31623164
271 + 31622893 = 31623164
283 + 31622881 = 31623164
421 + 31622743 = 31623164
523 + 31622641 = 31623164
673 + 31622491 = 31623164

Showing the first eight; more decompositions exist.
