Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514234, here are decompositions:

13 + 31514221 = 31514234
43 + 31514191 = 31514234
211 + 31514023 = 31514234
277 + 31513957 = 31514234
307 + 31513927 = 31514234
541 + 31513693 = 31514234
613 + 31513621 = 31514234
673 + 31513561 = 31514234

Showing the first eight; more decompositions exist.
