Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586376, here are decompositions:

37 + 31586339 = 31586376
89 + 31586287 = 31586376
103 + 31586273 = 31586376
139 + 31586237 = 31586376
229 + 31586147 = 31586376
317 + 31586059 = 31586376
373 + 31586003 = 31586376
379 + 31585997 = 31586376

Showing the first eight; more decompositions exist.
