Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586104, here are decompositions:

3 + 31586101 = 31586104
47 + 31586057 = 31586104
101 + 31586003 = 31586104
107 + 31585997 = 31586104
131 + 31585973 = 31586104
167 + 31585937 = 31586104
281 + 31585823 = 31586104
293 + 31585811 = 31586104

Showing the first eight; more decompositions exist.
