Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472252, here are decompositions:

13 + 31472239 = 31472252
43 + 31472209 = 31472252
61 + 31472191 = 31472252
73 + 31472179 = 31472252
103 + 31472149 = 31472252
109 + 31472143 = 31472252
199 + 31472053 = 31472252
211 + 31472041 = 31472252

Showing the first eight; more decompositions exist.
