Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514894, here are decompositions:

163 + 31514731 = 31514894
223 + 31514671 = 31514894
241 + 31514653 = 31514894
421 + 31514473 = 31514894
673 + 31514221 = 31514894
751 + 31514143 = 31514894
907 + 31513987 = 31514894
937 + 31513957 = 31514894

Showing the first eight; more decompositions exist.
