Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488622, here are decompositions:

3 + 31488619 = 31488622
59 + 31488563 = 31488622
251 + 31488371 = 31488622
293 + 31488329 = 31488622
419 + 31488203 = 31488622
461 + 31488161 = 31488622
521 + 31488101 = 31488622
563 + 31488059 = 31488622

Showing the first eight; more decompositions exist.
