Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560264, here are decompositions:

13 + 31560251 = 31560264
17 + 31560247 = 31560264
31 + 31560233 = 31560264
37 + 31560227 = 31560264
157 + 31560107 = 31560264
167 + 31560097 = 31560264
191 + 31560073 = 31560264
283 + 31559981 = 31560264

Showing the first eight; more decompositions exist.
