Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536226, here are decompositions:

3 + 31536223 = 31536226
23 + 31536203 = 31536226
173 + 31536053 = 31536226
317 + 31535909 = 31536226
347 + 31535879 = 31536226
479 + 31535747 = 31536226
509 + 31535717 = 31536226
569 + 31535657 = 31536226

Showing the first eight; more decompositions exist.
