Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479068, here are decompositions:

7 + 31479061 = 31479068
37 + 31479031 = 31479068
67 + 31479001 = 31479068
109 + 31478959 = 31479068
157 + 31478911 = 31479068
331 + 31478737 = 31479068
349 + 31478719 = 31479068
367 + 31478701 = 31479068

Showing the first eight; more decompositions exist.
