Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514018, here are decompositions:

31 + 31513987 = 31514018
61 + 31513957 = 31514018
127 + 31513891 = 31514018
139 + 31513879 = 31514018
199 + 31513819 = 31514018
397 + 31513621 = 31514018
439 + 31513579 = 31514018
457 + 31513561 = 31514018

Showing the first eight; more decompositions exist.
