Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546480, here are decompositions:

11 + 31546469 = 31546480
23 + 31546457 = 31546480
29 + 31546451 = 31546480
59 + 31546421 = 31546480
131 + 31546349 = 31546480
179 + 31546301 = 31546480
197 + 31546283 = 31546480
263 + 31546217 = 31546480

Showing the first eight; more decompositions exist.
