Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519694, here are decompositions:

7 + 31519687 = 31519694
127 + 31519567 = 31519694
163 + 31519531 = 31519694
211 + 31519483 = 31519694
277 + 31519417 = 31519694
313 + 31519381 = 31519694
331 + 31519363 = 31519694
337 + 31519357 = 31519694

Showing the first eight; more decompositions exist.
