Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546966, here are decompositions:

29 + 31546937 = 31546966
53 + 31546913 = 31546966
149 + 31546817 = 31546966
167 + 31546799 = 31546966
257 + 31546709 = 31546966
383 + 31546583 = 31546966
509 + 31546457 = 31546966
617 + 31546349 = 31546966

Showing the first eight; more decompositions exist.
