Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623422, here are decompositions:

79 + 31623343 = 31623422
199 + 31623223 = 31623422
211 + 31623211 = 31623422
223 + 31623199 = 31623422
241 + 31623181 = 31623422
463 + 31622959 = 31623422
499 + 31622923 = 31623422
541 + 31622881 = 31623422

Showing the first eight; more decompositions exist.
