Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479124, here are decompositions:

23 + 31479101 = 31479124
41 + 31479083 = 31479124
107 + 31479017 = 31479124
167 + 31478957 = 31479124
191 + 31478933 = 31479124
293 + 31478831 = 31479124
317 + 31478807 = 31479124
557 + 31478567 = 31479124

Showing the first eight; more decompositions exist.
