Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514408, here are decompositions:

7 + 31514401 = 31514408
307 + 31514101 = 31514408
349 + 31514059 = 31514408
421 + 31513987 = 31514408
577 + 31513831 = 31514408
787 + 31513621 = 31514408
829 + 31513579 = 31514408
997 + 31513411 = 31514408

Showing the first eight; more decompositions exist.
