Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514874, here are decompositions:

5 + 31514869 = 31514874
37 + 31514837 = 31514874
103 + 31514771 = 31514874
211 + 31514663 = 31514874
233 + 31514641 = 31514874
337 + 31514537 = 31514874
397 + 31514477 = 31514874
401 + 31514473 = 31514874

Showing the first eight; more decompositions exist.
