Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514230, here are decompositions:

71 + 31514159 = 31514230
149 + 31514081 = 31514230
263 + 31513967 = 31514230
353 + 31513877 = 31514230
443 + 31513787 = 31514230
491 + 31513739 = 31514230
509 + 31513721 = 31514230
521 + 31513709 = 31514230

Showing the first eight; more decompositions exist.
