Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590496, here are decompositions:

17 + 31590479 = 31590496
29 + 31590467 = 31590496
53 + 31590443 = 31590496
83 + 31590413 = 31590496
227 + 31590269 = 31590496
233 + 31590263 = 31590496
347 + 31590149 = 31590496
359 + 31590137 = 31590496

Showing the first eight; more decompositions exist.
