Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520034, here are decompositions:

5 + 31520029 = 31520034
17 + 31520017 = 31520034
23 + 31520011 = 31520034
47 + 31519987 = 31520034
83 + 31519951 = 31520034
97 + 31519937 = 31520034
101 + 31519933 = 31520034
107 + 31519927 = 31520034

Showing the first eight; more decompositions exist.
