Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523282, here are decompositions:

3 + 31523279 = 31523282
31 + 31523251 = 31523282
61 + 31523221 = 31523282
73 + 31523209 = 31523282
139 + 31523143 = 31523282
151 + 31523131 = 31523282
163 + 31523119 = 31523282
229 + 31523053 = 31523282

Showing the first eight; more decompositions exist.
