Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520382, here are decompositions:

11 + 31520371 = 31520382
29 + 31520353 = 31520382
43 + 31520339 = 31520382
73 + 31520309 = 31520382
83 + 31520299 = 31520382
139 + 31520243 = 31520382
149 + 31520233 = 31520382
181 + 31520201 = 31520382

Showing the first eight; more decompositions exist.
