Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520046, here are decompositions:

17 + 31520029 = 31520046
29 + 31520017 = 31520046
37 + 31520009 = 31520046
59 + 31519987 = 31520046
109 + 31519937 = 31520046
113 + 31519933 = 31520046
127 + 31519919 = 31520046
137 + 31519909 = 31520046

Showing the first eight; more decompositions exist.
