Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586476, here are decompositions:

3 + 31586473 = 31586476
29 + 31586447 = 31586476
137 + 31586339 = 31586476
239 + 31586237 = 31586476
419 + 31586057 = 31586476
479 + 31585997 = 31586476
503 + 31585973 = 31586476
587 + 31585889 = 31586476

Showing the first eight; more decompositions exist.
