Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479346, here are decompositions:

47 + 31479299 = 31479346
149 + 31479197 = 31479346
263 + 31479083 = 31479346
389 + 31478957 = 31479346
863 + 31478483 = 31479346
947 + 31478399 = 31479346
953 + 31478393 = 31479346
1013 + 31478333 = 31479346

Showing the first eight; more decompositions exist.
