Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615510, here are decompositions:

71 + 31615439 = 31615510
107 + 31615403 = 31615510
167 + 31615343 = 31615510
197 + 31615313 = 31615510
281 + 31615229 = 31615510
293 + 31615217 = 31615510
317 + 31615193 = 31615510
347 + 31615163 = 31615510

Showing the first eight; more decompositions exist.
