Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493182, here are decompositions:

11 + 31493171 = 31493182
29 + 31493153 = 31493182
113 + 31493069 = 31493182
173 + 31493009 = 31493182
191 + 31492991 = 31493182
239 + 31492943 = 31493182
401 + 31492781 = 31493182
431 + 31492751 = 31493182

Showing the first eight; more decompositions exist.
