Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520196, here are decompositions:

17 + 31520179 = 31520196
23 + 31520173 = 31520196
79 + 31520117 = 31520196
107 + 31520089 = 31520196
137 + 31520059 = 31520196
167 + 31520029 = 31520196
179 + 31520017 = 31520196
263 + 31519933 = 31520196

Showing the first eight; more decompositions exist.
