Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523382, here are decompositions:

53 + 31523329 = 31523382
73 + 31523309 = 31523382
89 + 31523293 = 31523382
103 + 31523279 = 31523382
131 + 31523251 = 31523382
139 + 31523243 = 31523382
151 + 31523231 = 31523382
173 + 31523209 = 31523382

Showing the first eight; more decompositions exist.
