Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479336, here are decompositions:

29 + 31479307 = 31479336
37 + 31479299 = 31479336
47 + 31479289 = 31479336
59 + 31479277 = 31479336
67 + 31479269 = 31479336
139 + 31479197 = 31479336
263 + 31479073 = 31479336
353 + 31478983 = 31479336

Showing the first eight; more decompositions exist.
