Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562332, here are decompositions:

3 + 31562329 = 31562332
41 + 31562291 = 31562332
59 + 31562273 = 31562332
71 + 31562261 = 31562332
89 + 31562243 = 31562332
101 + 31562231 = 31562332
233 + 31562099 = 31562332
239 + 31562093 = 31562332

Showing the first eight; more decompositions exist.
