Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473954, here are decompositions:

23 + 31473931 = 31473954
37 + 31473917 = 31473954
47 + 31473907 = 31473954
53 + 31473901 = 31473954
67 + 31473887 = 31473954
107 + 31473847 = 31473954
173 + 31473781 = 31473954
251 + 31473703 = 31473954

Showing the first eight; more decompositions exist.
