Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613566, here are decompositions:

53 + 31613513 = 31613566
167 + 31613399 = 31613566
233 + 31613333 = 31613566
317 + 31613249 = 31613566
449 + 31613117 = 31613566
653 + 31612913 = 31613566
827 + 31612739 = 31613566
839 + 31612727 = 31613566

Showing the first eight; more decompositions exist.
