Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619516, here are decompositions:

7 + 31619509 = 31619516
109 + 31619407 = 31619516
127 + 31619389 = 31619516
157 + 31619359 = 31619516
307 + 31619209 = 31619516
337 + 31619179 = 31619516
373 + 31619143 = 31619516
499 + 31619017 = 31619516

Showing the first eight; more decompositions exist.
