Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493682, here are decompositions:

5 + 31493677 = 31493682
29 + 31493653 = 31493682
41 + 31493641 = 31493682
71 + 31493611 = 31493682
83 + 31493599 = 31493682
89 + 31493593 = 31493682
109 + 31493573 = 31493682
113 + 31493569 = 31493682

Showing the first eight; more decompositions exist.
