Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479204, here are decompositions:

7 + 31479197 = 31479204
73 + 31479131 = 31479204
103 + 31479101 = 31479204
131 + 31479073 = 31479204
173 + 31479031 = 31479204
271 + 31478933 = 31479204
293 + 31478911 = 31479204
353 + 31478851 = 31479204

Showing the first eight; more decompositions exist.
