Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546428, here are decompositions:

7 + 31546421 = 31546428
41 + 31546387 = 31546428
59 + 31546369 = 31546428
79 + 31546349 = 31546428
127 + 31546301 = 31546428
149 + 31546279 = 31546428
197 + 31546231 = 31546428
211 + 31546217 = 31546428

Showing the first eight; more decompositions exist.
