Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562824, here are decompositions:

23 + 31562801 = 31562824
47 + 31562777 = 31562824
113 + 31562711 = 31562824
197 + 31562627 = 31562824
257 + 31562567 = 31562824
281 + 31562543 = 31562824
383 + 31562441 = 31562824
401 + 31562423 = 31562824

Showing the first eight; more decompositions exist.
