Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619064, here are decompositions:

23 + 31619041 = 31619064
47 + 31619017 = 31619064
73 + 31618991 = 31619064
83 + 31618981 = 31619064
163 + 31618901 = 31619064
167 + 31618897 = 31619064
173 + 31618891 = 31619064
181 + 31618883 = 31619064

Showing the first eight; more decompositions exist.
