Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588526, here are decompositions:

3 + 31588523 = 31588526
43 + 31588483 = 31588526
127 + 31588399 = 31588526
157 + 31588369 = 31588526
223 + 31588303 = 31588526
397 + 31588129 = 31588526
439 + 31588087 = 31588526
523 + 31588003 = 31588526

Showing the first eight; more decompositions exist.
