Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562548, here are decompositions:

5 + 31562543 = 31562548
29 + 31562519 = 31562548
47 + 31562501 = 31562548
107 + 31562441 = 31562548
191 + 31562357 = 31562548
257 + 31562291 = 31562548
317 + 31562231 = 31562548
431 + 31562117 = 31562548

Showing the first eight; more decompositions exist.
