Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613416, here are decompositions:

5 + 31613411 = 31613416
17 + 31613399 = 31613416
59 + 31613357 = 31613416
83 + 31613333 = 31613416
167 + 31613249 = 31613416
173 + 31613243 = 31613416
389 + 31613027 = 31613416
503 + 31612913 = 31613416

Showing the first eight; more decompositions exist.
