Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543954, here are decompositions:

41 + 31543913 = 31543954
47 + 31543907 = 31543954
83 + 31543871 = 31543954
107 + 31543847 = 31543954
137 + 31543817 = 31543954
191 + 31543763 = 31543954
257 + 31543697 = 31543954
263 + 31543691 = 31543954

Showing the first eight; more decompositions exist.
