Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479916, here are decompositions:

59 + 31479857 = 31479916
113 + 31479803 = 31479916
173 + 31479743 = 31479916
179 + 31479737 = 31479916
197 + 31479719 = 31479916
269 + 31479647 = 31479916
359 + 31479557 = 31479916
449 + 31479467 = 31479916

Showing the first eight; more decompositions exist.
