Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516914, here are decompositions:

73 + 31516841 = 31516914
103 + 31516811 = 31516914
127 + 31516787 = 31516914
137 + 31516777 = 31516914
157 + 31516757 = 31516914
211 + 31516703 = 31516914
281 + 31516633 = 31516914
283 + 31516631 = 31516914

Showing the first eight; more decompositions exist.
