Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574310, here are decompositions:

7 + 31574303 = 31574310
13 + 31574297 = 31574310
107 + 31574203 = 31574310
109 + 31574201 = 31574310
137 + 31574173 = 31574310
179 + 31574131 = 31574310
211 + 31574099 = 31574310
239 + 31574071 = 31574310

Showing the first eight; more decompositions exist.
