Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613146, here are decompositions:

3 + 31613143 = 31613146
29 + 31613117 = 31613146
233 + 31612913 = 31613146
293 + 31612853 = 31613146
419 + 31612727 = 31613146
479 + 31612667 = 31613146
557 + 31612589 = 31613146
563 + 31612583 = 31613146

Showing the first eight; more decompositions exist.
