Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474068, here are decompositions:

7 + 31474061 = 31474068
11 + 31474057 = 31474068
61 + 31474007 = 31474068
97 + 31473971 = 31474068
137 + 31473931 = 31474068
151 + 31473917 = 31474068
167 + 31473901 = 31474068
181 + 31473887 = 31474068

Showing the first eight; more decompositions exist.
