Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464028, here are decompositions:

107 + 31463921 = 31464028
131 + 31463897 = 31464028
137 + 31463891 = 31464028
149 + 31463879 = 31464028
179 + 31463849 = 31464028
269 + 31463759 = 31464028
311 + 31463717 = 31464028
347 + 31463681 = 31464028

Showing the first eight; more decompositions exist.
