Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562536, here are decompositions:

17 + 31562519 = 31562536
53 + 31562483 = 31562536
107 + 31562429 = 31562536
113 + 31562423 = 31562536
179 + 31562357 = 31562536
263 + 31562273 = 31562536
293 + 31562243 = 31562536
419 + 31562117 = 31562536

Showing the first eight; more decompositions exist.
