Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479108, here are decompositions:

7 + 31479101 = 31479108
47 + 31479061 = 31479108
107 + 31479001 = 31479108
139 + 31478969 = 31479108
149 + 31478959 = 31479108
151 + 31478957 = 31479108
197 + 31478911 = 31479108
257 + 31478851 = 31479108

Showing the first eight; more decompositions exist.
