Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463954, here are decompositions:

13 + 31463941 = 31463954
43 + 31463911 = 31463954
61 + 31463893 = 31463954
97 + 31463857 = 31463954
127 + 31463827 = 31463954
157 + 31463797 = 31463954
211 + 31463743 = 31463954
241 + 31463713 = 31463954

Showing the first eight; more decompositions exist.
