Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479006, here are decompositions:

5 + 31479001 = 31479006
23 + 31478983 = 31479006
37 + 31478969 = 31479006
47 + 31478959 = 31479006
73 + 31478933 = 31479006
199 + 31478807 = 31479006
269 + 31478737 = 31479006
359 + 31478647 = 31479006

Showing the first eight; more decompositions exist.
