Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546398, here are decompositions:

5 + 31546393 = 31546398
11 + 31546387 = 31546398
29 + 31546369 = 31546398
47 + 31546351 = 31546398
61 + 31546337 = 31546398
97 + 31546301 = 31546398
131 + 31546267 = 31546398
167 + 31546231 = 31546398

Showing the first eight; more decompositions exist.
