Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560346, here are decompositions:

3 + 31560343 = 31560346
5 + 31560341 = 31560346
47 + 31560299 = 31560346
53 + 31560293 = 31560346
107 + 31560239 = 31560346
113 + 31560233 = 31560346
173 + 31560173 = 31560346
239 + 31560107 = 31560346

Showing the first eight; more decompositions exist.
