Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518976, here are decompositions:

23 + 31518953 = 31518976
53 + 31518923 = 31518976
107 + 31518869 = 31518976
113 + 31518863 = 31518976
149 + 31518827 = 31518976
197 + 31518779 = 31518976
317 + 31518659 = 31518976
383 + 31518593 = 31518976

Showing the first eight; more decompositions exist.
