Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560054, here are decompositions:

7 + 31560047 = 31560054
73 + 31559981 = 31560054
103 + 31559951 = 31560054
193 + 31559861 = 31560054
223 + 31559831 = 31560054
233 + 31559821 = 31560054
241 + 31559813 = 31560054
271 + 31559783 = 31560054

Showing the first eight; more decompositions exist.
