Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547184, here are decompositions:

7 + 31547177 = 31547184
23 + 31547161 = 31547184
37 + 31547147 = 31547184
41 + 31547143 = 31547184
83 + 31547101 = 31547184
107 + 31547077 = 31547184
181 + 31547003 = 31547184
197 + 31546987 = 31547184

Showing the first eight; more decompositions exist.
