Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562352, here are decompositions:

5 + 31562347 = 31562352
23 + 31562329 = 31562352
53 + 31562299 = 31562352
61 + 31562291 = 31562352
71 + 31562281 = 31562352
79 + 31562273 = 31562352
89 + 31562263 = 31562352
109 + 31562243 = 31562352

Showing the first eight; more decompositions exist.
