Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623122, here are decompositions:

61 + 31623061 = 31623122
163 + 31622959 = 31623122
199 + 31622923 = 31623122
229 + 31622893 = 31623122
241 + 31622881 = 31623122
313 + 31622809 = 31623122
379 + 31622743 = 31623122
409 + 31622713 = 31623122

Showing the first eight; more decompositions exist.
