Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546458, here are decompositions:

7 + 31546451 = 31546458
37 + 31546421 = 31546458
71 + 31546387 = 31546458
89 + 31546369 = 31546458
107 + 31546351 = 31546458
109 + 31546349 = 31546458
157 + 31546301 = 31546458
179 + 31546279 = 31546458

Showing the first eight; more decompositions exist.
