Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560348, here are decompositions:

5 + 31560343 = 31560348
7 + 31560341 = 31560348
41 + 31560307 = 31560348
97 + 31560251 = 31560348
101 + 31560247 = 31560348
109 + 31560239 = 31560348
241 + 31560107 = 31560348
251 + 31560097 = 31560348

Showing the first eight; more decompositions exist.
