Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546460, here are decompositions:

3 + 31546457 = 31546460
67 + 31546393 = 31546460
73 + 31546387 = 31546460
109 + 31546351 = 31546460
157 + 31546303 = 31546460
181 + 31546279 = 31546460
193 + 31546267 = 31546460
229 + 31546231 = 31546460

Showing the first eight; more decompositions exist.
