Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536622, here are decompositions:

71 + 31536551 = 31536622
83 + 31536539 = 31536622
101 + 31536521 = 31536622
239 + 31536383 = 31536622
263 + 31536359 = 31536622
269 + 31536353 = 31536622
419 + 31536203 = 31536622
461 + 31536161 = 31536622

Showing the first eight; more decompositions exist.
