Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547274, here are decompositions:

7 + 31547267 = 31547274
13 + 31547261 = 31547274
43 + 31547231 = 31547274
71 + 31547203 = 31547274
97 + 31547177 = 31547274
113 + 31547161 = 31547274
127 + 31547147 = 31547274
131 + 31547143 = 31547274

Showing the first eight; more decompositions exist.
