Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493676, here are decompositions:

23 + 31493653 = 31493676
83 + 31493593 = 31493676
103 + 31493573 = 31493676
107 + 31493569 = 31493676
157 + 31493519 = 31493676
163 + 31493513 = 31493676
199 + 31493477 = 31493676
229 + 31493447 = 31493676

Showing the first eight; more decompositions exist.
