Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514828, here are decompositions:

97 + 31514731 = 31514828
139 + 31514689 = 31514828
157 + 31514671 = 31514828
199 + 31514629 = 31514828
229 + 31514599 = 31514828
277 + 31514551 = 31514828
349 + 31514479 = 31514828
379 + 31514449 = 31514828

Showing the first eight; more decompositions exist.
