Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479996, here are decompositions:

47 + 31479949 = 31479996
139 + 31479857 = 31479996
167 + 31479829 = 31479996
179 + 31479817 = 31479996
193 + 31479803 = 31479996
227 + 31479769 = 31479996
239 + 31479757 = 31479996
257 + 31479739 = 31479996

Showing the first eight; more decompositions exist.
