Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586374, here are decompositions:

23 + 31586351 = 31586374
101 + 31586273 = 31586374
137 + 31586237 = 31586374
227 + 31586147 = 31586374
233 + 31586141 = 31586374
317 + 31586057 = 31586374
401 + 31585973 = 31586374
557 + 31585817 = 31586374

Showing the first eight; more decompositions exist.
