Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546406, here are decompositions:

13 + 31546393 = 31546406
19 + 31546387 = 31546406
37 + 31546369 = 31546406
103 + 31546303 = 31546406
127 + 31546279 = 31546406
139 + 31546267 = 31546406
277 + 31546129 = 31546406
337 + 31546069 = 31546406

Showing the first eight; more decompositions exist.
