Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517162, here are decompositions:

13 + 31517149 = 31517162
151 + 31517011 = 31517162
181 + 31516981 = 31517162
211 + 31516951 = 31517162
283 + 31516879 = 31517162
373 + 31516789 = 31517162
409 + 31516753 = 31517162
433 + 31516729 = 31517162

Showing the first eight; more decompositions exist.
