Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536724, here are decompositions:

5 + 31536719 = 31536724
17 + 31536707 = 31536724
173 + 31536551 = 31536724
431 + 31536293 = 31536724
521 + 31536203 = 31536724
563 + 31536161 = 31536724
743 + 31535981 = 31536724
971 + 31535753 = 31536724

Showing the first eight; more decompositions exist.
