Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546498, here are decompositions:

29 + 31546469 = 31546498
41 + 31546457 = 31546498
47 + 31546451 = 31546498
149 + 31546349 = 31546498
197 + 31546301 = 31546498
281 + 31546217 = 31546498
311 + 31546187 = 31546498
317 + 31546181 = 31546498

Showing the first eight; more decompositions exist.
