Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514998, here are decompositions:

17 + 31514981 = 31514998
29 + 31514969 = 31514998
149 + 31514849 = 31514998
227 + 31514771 = 31514998
257 + 31514741 = 31514998
311 + 31514687 = 31514998
419 + 31514579 = 31514998
461 + 31514537 = 31514998

Showing the first eight; more decompositions exist.
