Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493694, here are decompositions:

5 + 31493689 = 31493694
17 + 31493677 = 31493694
41 + 31493653 = 31493694
53 + 31493641 = 31493694
83 + 31493611 = 31493694
101 + 31493593 = 31493694
137 + 31493557 = 31493694
173 + 31493521 = 31493694

Showing the first eight; more decompositions exist.
