Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479074, here are decompositions:

13 + 31479061 = 31479074
43 + 31479031 = 31479074
73 + 31479001 = 31479074
163 + 31478911 = 31479074
223 + 31478851 = 31479074
337 + 31478737 = 31479074
373 + 31478701 = 31479074
673 + 31478401 = 31479074

Showing the first eight; more decompositions exist.
