Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514930, here are decompositions:

19 + 31514911 = 31514930
37 + 31514893 = 31514930
61 + 31514869 = 31514930
199 + 31514731 = 31514930
241 + 31514689 = 31514930
277 + 31514653 = 31514930
331 + 31514599 = 31514930
379 + 31514551 = 31514930

Showing the first eight; more decompositions exist.
