Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479234, here are decompositions:

37 + 31479197 = 31479234
103 + 31479131 = 31479234
107 + 31479127 = 31479234
151 + 31479083 = 31479234
173 + 31479061 = 31479234
233 + 31479001 = 31479234
251 + 31478983 = 31479234
277 + 31478957 = 31479234

Showing the first eight; more decompositions exist.
