Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514900, here are decompositions:

7 + 31514893 = 31514900
31 + 31514869 = 31514900
61 + 31514839 = 31514900
211 + 31514689 = 31514900
229 + 31514671 = 31514900
271 + 31514629 = 31514900
349 + 31514551 = 31514900
367 + 31514533 = 31514900

Showing the first eight; more decompositions exist.
