Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613746, here are decompositions:

29 + 31613717 = 31613746
107 + 31613639 = 31613746
167 + 31613579 = 31613746
233 + 31613513 = 31613746
347 + 31613399 = 31613746
389 + 31613357 = 31613746
503 + 31613243 = 31613746
719 + 31613027 = 31613746

Showing the first eight; more decompositions exist.
