Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590532, here are decompositions:

53 + 31590479 = 31590532
89 + 31590443 = 31590532
131 + 31590401 = 31590532
179 + 31590353 = 31590532
263 + 31590269 = 31590532
269 + 31590263 = 31590532
383 + 31590149 = 31590532
443 + 31590089 = 31590532

Showing the first eight; more decompositions exist.
