Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514504, here are decompositions:

31 + 31514473 = 31514504
103 + 31514401 = 31514504
283 + 31514221 = 31514504
313 + 31514191 = 31514504
547 + 31513957 = 31514504
577 + 31513927 = 31514504
613 + 31513891 = 31514504
631 + 31513873 = 31514504

Showing the first eight; more decompositions exist.
