Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586460, here are decompositions:

13 + 31586447 = 31586460
53 + 31586407 = 31586460
83 + 31586377 = 31586460
109 + 31586351 = 31586460
149 + 31586311 = 31586460
173 + 31586287 = 31586460
179 + 31586281 = 31586460
223 + 31586237 = 31586460

Showing the first eight; more decompositions exist.
