Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547182, here are decompositions:

5 + 31547177 = 31547182
53 + 31547129 = 31547182
89 + 31547093 = 31547182
179 + 31547003 = 31547182
269 + 31546913 = 31547182
383 + 31546799 = 31547182
461 + 31546721 = 31547182
521 + 31546661 = 31547182

Showing the first eight; more decompositions exist.
