Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479850, here are decompositions:

29 + 31479821 = 31479850
47 + 31479803 = 31479850
107 + 31479743 = 31479850
113 + 31479737 = 31479850
131 + 31479719 = 31479850
179 + 31479671 = 31479850
257 + 31479593 = 31479850
293 + 31479557 = 31479850

Showing the first eight; more decompositions exist.
