Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479896, here are decompositions:

67 + 31479829 = 31479896
79 + 31479817 = 31479896
103 + 31479793 = 31479896
127 + 31479769 = 31479896
139 + 31479757 = 31479896
157 + 31479739 = 31479896
199 + 31479697 = 31479896
277 + 31479619 = 31479896

Showing the first eight; more decompositions exist.
