Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493696, here are decompositions:

7 + 31493689 = 31493696
19 + 31493677 = 31493696
43 + 31493653 = 31493696
97 + 31493599 = 31493696
103 + 31493593 = 31493696
127 + 31493569 = 31493696
139 + 31493557 = 31493696
163 + 31493533 = 31493696

Showing the first eight; more decompositions exist.
