Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536382, here are decompositions:

23 + 31536359 = 31536382
29 + 31536353 = 31536382
89 + 31536293 = 31536382
179 + 31536203 = 31536382
281 + 31536101 = 31536382
401 + 31535981 = 31536382
443 + 31535939 = 31536382
503 + 31535879 = 31536382

Showing the first eight; more decompositions exist.
