Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514326, here are decompositions:

17 + 31514309 = 31514326
29 + 31514297 = 31514326
59 + 31514267 = 31514326
167 + 31514159 = 31514326
359 + 31513967 = 31514326
383 + 31513943 = 31514326
449 + 31513877 = 31514326
509 + 31513817 = 31514326

Showing the first eight; more decompositions exist.
