Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514528, here are decompositions:

79 + 31514449 = 31514528
109 + 31514419 = 31514528
127 + 31514401 = 31514528
307 + 31514221 = 31514528
337 + 31514191 = 31514528
379 + 31514149 = 31514528
541 + 31513987 = 31514528
571 + 31513957 = 31514528

Showing the first eight; more decompositions exist.
