Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619694, here are decompositions:

11 + 31619683 = 31619694
47 + 31619647 = 31619694
83 + 31619611 = 31619694
137 + 31619557 = 31619694
151 + 31619543 = 31619694
163 + 31619531 = 31619694
167 + 31619527 = 31619694
173 + 31619521 = 31619694

Showing the first eight; more decompositions exist.
