Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519834, here are decompositions:

11 + 31519823 = 31519834
41 + 31519793 = 31519834
131 + 31519703 = 31519834
173 + 31519661 = 31519834
233 + 31519601 = 31519834
251 + 31519583 = 31519834
263 + 31519571 = 31519834
347 + 31519487 = 31519834

Showing the first eight; more decompositions exist.
