Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479246, here are decompositions:

5 + 31479241 = 31479246
163 + 31479083 = 31479246
173 + 31479073 = 31479246
229 + 31479017 = 31479246
263 + 31478983 = 31479246
277 + 31478969 = 31479246
313 + 31478933 = 31479246
439 + 31478807 = 31479246

Showing the first eight; more decompositions exist.
