Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562426, here are decompositions:

3 + 31562423 = 31562426
37 + 31562389 = 31562426
79 + 31562347 = 31562426
97 + 31562329 = 31562426
127 + 31562299 = 31562426
163 + 31562263 = 31562426
307 + 31562119 = 31562426
373 + 31562053 = 31562426

Showing the first eight; more decompositions exist.
