Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520582, here are decompositions:

3 + 31520579 = 31520582
13 + 31520569 = 31520582
73 + 31520509 = 31520582
103 + 31520479 = 31520582
193 + 31520389 = 31520582
211 + 31520371 = 31520582
229 + 31520353 = 31520582
283 + 31520299 = 31520582

Showing the first eight; more decompositions exist.
