Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619794, here are decompositions:

5 + 31619789 = 31619794
23 + 31619771 = 31619794
53 + 31619741 = 31619794
71 + 31619723 = 31619794
191 + 31619603 = 31619794
233 + 31619561 = 31619794
251 + 31619543 = 31619794
263 + 31619531 = 31619794

Showing the first eight; more decompositions exist.
