Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546954, here are decompositions:

17 + 31546937 = 31546954
41 + 31546913 = 31546954
107 + 31546847 = 31546954
137 + 31546817 = 31546954
233 + 31546721 = 31546954
293 + 31546661 = 31546954
317 + 31546637 = 31546954
353 + 31546601 = 31546954

Showing the first eight; more decompositions exist.
