Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493706, here are decompositions:

17 + 31493689 = 31493706
29 + 31493677 = 31493706
53 + 31493653 = 31493706
107 + 31493599 = 31493706
113 + 31493593 = 31493706
137 + 31493569 = 31493706
149 + 31493557 = 31493706
173 + 31493533 = 31493706

Showing the first eight; more decompositions exist.
