Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493724, here are decompositions:

7 + 31493717 = 31493724
13 + 31493711 = 31493724
47 + 31493677 = 31493724
71 + 31493653 = 31493724
83 + 31493641 = 31493724
113 + 31493611 = 31493724
131 + 31493593 = 31493724
151 + 31493573 = 31493724

Showing the first eight; more decompositions exist.
