Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546918, here are decompositions:

5 + 31546913 = 31546918
71 + 31546847 = 31546918
101 + 31546817 = 31546918
197 + 31546721 = 31546918
257 + 31546661 = 31546918
281 + 31546637 = 31546918
317 + 31546601 = 31546918
449 + 31546469 = 31546918

Showing the first eight; more decompositions exist.
