Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619536, here are decompositions:

5 + 31619531 = 31619536
17 + 31619519 = 31619536
149 + 31619387 = 31619536
269 + 31619267 = 31619536
353 + 31619183 = 31619536
359 + 31619177 = 31619536
419 + 31619117 = 31619536
587 + 31618949 = 31619536

Showing the first eight; more decompositions exist.
