Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547050, here are decompositions:

11 + 31547039 = 31547050
47 + 31547003 = 31547050
53 + 31546997 = 31547050
113 + 31546937 = 31547050
137 + 31546913 = 31547050
233 + 31546817 = 31547050
251 + 31546799 = 31547050
389 + 31546661 = 31547050

Showing the first eight; more decompositions exist.
