Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586052, here are decompositions:

73 + 31585979 = 31586052
79 + 31585973 = 31586052
89 + 31585963 = 31586052
149 + 31585903 = 31586052
163 + 31585889 = 31586052
229 + 31585823 = 31586052
241 + 31585811 = 31586052
269 + 31585783 = 31586052

Showing the first eight; more decompositions exist.
