Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520076, here are decompositions:

17 + 31520059 = 31520076
47 + 31520029 = 31520076
59 + 31520017 = 31520076
67 + 31520009 = 31520076
89 + 31519987 = 31520076
139 + 31519937 = 31520076
149 + 31519927 = 31520076
157 + 31519919 = 31520076

Showing the first eight; more decompositions exist.
