Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520246, here are decompositions:

3 + 31520243 = 31520246
13 + 31520233 = 31520246
67 + 31520179 = 31520246
73 + 31520173 = 31520246
127 + 31520119 = 31520246
157 + 31520089 = 31520246
229 + 31520017 = 31520246
313 + 31519933 = 31520246

Showing the first eight; more decompositions exist.
