Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588632, here are decompositions:

29 + 31588603 = 31588632
71 + 31588561 = 31588632
109 + 31588523 = 31588632
139 + 31588493 = 31588632
149 + 31588483 = 31588632
191 + 31588441 = 31588632
193 + 31588439 = 31588632
233 + 31588399 = 31588632

Showing the first eight; more decompositions exist.
