Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560050, here are decompositions:

3 + 31560047 = 31560050
31 + 31560019 = 31560050
61 + 31559989 = 31560050
73 + 31559977 = 31560050
139 + 31559911 = 31560050
199 + 31559851 = 31560050
229 + 31559821 = 31560050
241 + 31559809 = 31560050

Showing the first eight; more decompositions exist.
