Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562284, here are decompositions:

3 + 31562281 = 31562284
11 + 31562273 = 31562284
23 + 31562261 = 31562284
41 + 31562243 = 31562284
53 + 31562231 = 31562284
71 + 31562213 = 31562284
167 + 31562117 = 31562284
191 + 31562093 = 31562284

Showing the first eight; more decompositions exist.
