Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536652, here are decompositions:

23 + 31536629 = 31536652
101 + 31536551 = 31536652
113 + 31536539 = 31536652
131 + 31536521 = 31536652
269 + 31536383 = 31536652
293 + 31536359 = 31536652
359 + 31536293 = 31536652
449 + 31536203 = 31536652

Showing the first eight; more decompositions exist.
