Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474054, here are decompositions:

11 + 31474043 = 31474054
47 + 31474007 = 31474054
83 + 31473971 = 31474054
137 + 31473917 = 31474054
167 + 31473887 = 31474054
191 + 31473863 = 31474054
347 + 31473707 = 31474054
461 + 31473593 = 31474054

Showing the first eight; more decompositions exist.
