Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619566, here are decompositions:

5 + 31619561 = 31619566
23 + 31619543 = 31619566
47 + 31619519 = 31619566
107 + 31619459 = 31619566
179 + 31619387 = 31619566
239 + 31619327 = 31619566
353 + 31619213 = 31619566
359 + 31619207 = 31619566

Showing the first eight; more decompositions exist.
