Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479048, here are decompositions:

17 + 31479031 = 31479048
31 + 31479017 = 31479048
47 + 31479001 = 31479048
79 + 31478969 = 31479048
89 + 31478959 = 31479048
137 + 31478911 = 31479048
197 + 31478851 = 31479048
241 + 31478807 = 31479048

Showing the first eight; more decompositions exist.
