Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514194, here are decompositions:

3 + 31514191 = 31514194
113 + 31514081 = 31514194
227 + 31513967 = 31514194
251 + 31513943 = 31514194
317 + 31513877 = 31514194
401 + 31513793 = 31514194
587 + 31513607 = 31514194
821 + 31513373 = 31514194

Showing the first eight; more decompositions exist.
