Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493996, here are decompositions:

7 + 31493989 = 31493996
13 + 31493983 = 31493996
97 + 31493899 = 31493996
139 + 31493857 = 31493996
307 + 31493689 = 31493996
397 + 31493599 = 31493996
439 + 31493557 = 31493996
463 + 31493533 = 31493996

Showing the first eight; more decompositions exist.
