Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520088, here are decompositions:

29 + 31520059 = 31520088
59 + 31520029 = 31520088
71 + 31520017 = 31520088
79 + 31520009 = 31520088
101 + 31519987 = 31520088
137 + 31519951 = 31520088
151 + 31519937 = 31520088
179 + 31519909 = 31520088

Showing the first eight; more decompositions exist.
