Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472310, here are decompositions:

17 + 31472293 = 31472310
19 + 31472291 = 31472310
71 + 31472239 = 31472310
101 + 31472209 = 31472310
109 + 31472201 = 31472310
127 + 31472183 = 31472310
131 + 31472179 = 31472310
151 + 31472159 = 31472310

Showing the first eight; more decompositions exist.
