Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546600, here are decompositions:

3 + 31546597 = 31546600
17 + 31546583 = 31546600
47 + 31546553 = 31546600
131 + 31546469 = 31546600
149 + 31546451 = 31546600
179 + 31546421 = 31546600
251 + 31546349 = 31546600
263 + 31546337 = 31546600

Showing the first eight; more decompositions exist.
