Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546356, here are decompositions:

5 + 31546351 = 31546356
7 + 31546349 = 31546356
19 + 31546337 = 31546356
53 + 31546303 = 31546356
73 + 31546283 = 31546356
89 + 31546267 = 31546356
139 + 31546217 = 31546356
157 + 31546199 = 31546356

Showing the first eight; more decompositions exist.
