Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559532, here are decompositions:

31 + 31559501 = 31559532
61 + 31559471 = 31559532
89 + 31559443 = 31559532
131 + 31559401 = 31559532
149 + 31559383 = 31559532
181 + 31559351 = 31559532
211 + 31559321 = 31559532
269 + 31559263 = 31559532

Showing the first eight; more decompositions exist.
