Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562296, here are decompositions:

5 + 31562291 = 31562296
23 + 31562273 = 31562296
53 + 31562243 = 31562296
83 + 31562213 = 31562296
179 + 31562117 = 31562296
197 + 31562099 = 31562296
239 + 31562057 = 31562296
263 + 31562033 = 31562296

Showing the first eight; more decompositions exist.
