Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619166, here are decompositions:

23 + 31619143 = 31619166
37 + 31619129 = 31619166
43 + 31619123 = 31619166
149 + 31619017 = 31619166
157 + 31619009 = 31619166
167 + 31618999 = 31619166
223 + 31618943 = 31619166
269 + 31618897 = 31619166

Showing the first eight; more decompositions exist.
