Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546648, here are decompositions:

11 + 31546637 = 31546648
47 + 31546601 = 31546648
179 + 31546469 = 31546648
191 + 31546457 = 31546648
197 + 31546451 = 31546648
227 + 31546421 = 31546648
311 + 31546337 = 31546648
347 + 31546301 = 31546648

Showing the first eight; more decompositions exist.
