Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514544, here are decompositions:

7 + 31514537 = 31514544
11 + 31514533 = 31514544
31 + 31514513 = 31514544
67 + 31514477 = 31514544
71 + 31514473 = 31514544
277 + 31514267 = 31514544
283 + 31514261 = 31514544
353 + 31514191 = 31514544

Showing the first eight; more decompositions exist.
