Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623464, here are decompositions:

3 + 31623461 = 31623464
43 + 31623421 = 31623464
127 + 31623337 = 31623464
241 + 31623223 = 31623464
283 + 31623181 = 31623464
541 + 31622923 = 31623464
571 + 31622893 = 31623464
601 + 31622863 = 31623464

Showing the first eight; more decompositions exist.
