Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546382, here are decompositions:

13 + 31546369 = 31546382
31 + 31546351 = 31546382
79 + 31546303 = 31546382
103 + 31546279 = 31546382
151 + 31546231 = 31546382
223 + 31546159 = 31546382
229 + 31546153 = 31546382
271 + 31546111 = 31546382

Showing the first eight; more decompositions exist.
