Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514098, here are decompositions:

17 + 31514081 = 31514098
131 + 31513967 = 31514098
281 + 31513817 = 31514098
311 + 31513787 = 31514098
359 + 31513739 = 31514098
389 + 31513709 = 31514098
401 + 31513697 = 31514098
431 + 31513667 = 31514098

Showing the first eight; more decompositions exist.
