Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479252, here are decompositions:

11 + 31479241 = 31479252
151 + 31479101 = 31479252
179 + 31479073 = 31479252
191 + 31479061 = 31479252
251 + 31479001 = 31479252
269 + 31478983 = 31479252
283 + 31478969 = 31479252
293 + 31478959 = 31479252

Showing the first eight; more decompositions exist.
