Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560562, here are decompositions:

3 + 31560559 = 31560562
29 + 31560533 = 31560562
53 + 31560509 = 31560562
179 + 31560383 = 31560562
263 + 31560299 = 31560562
269 + 31560293 = 31560562
311 + 31560251 = 31560562
389 + 31560173 = 31560562

Showing the first eight; more decompositions exist.
