Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562526, here are decompositions:

7 + 31562519 = 31562526
43 + 31562483 = 31562526
59 + 31562467 = 31562526
97 + 31562429 = 31562526
103 + 31562423 = 31562526
137 + 31562389 = 31562526
179 + 31562347 = 31562526
197 + 31562329 = 31562526

Showing the first eight; more decompositions exist.
