Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566914, here are decompositions:

3 + 31566911 = 31566914
13 + 31566901 = 31566914
97 + 31566817 = 31566914
151 + 31566763 = 31566914
283 + 31566631 = 31566914
367 + 31566547 = 31566914
373 + 31566541 = 31566914
397 + 31566517 = 31566914

Showing the first eight; more decompositions exist.
