Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560084, here are decompositions:

5 + 31560079 = 31560084
11 + 31560073 = 31560084
37 + 31560047 = 31560084
103 + 31559981 = 31560084
107 + 31559977 = 31560084
173 + 31559911 = 31560084
223 + 31559861 = 31560084
233 + 31559851 = 31560084

Showing the first eight; more decompositions exist.
