Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588702, here are decompositions:

3 + 31588699 = 31588702
23 + 31588679 = 31588702
29 + 31588673 = 31588702
59 + 31588643 = 31588702
71 + 31588631 = 31588702
179 + 31588523 = 31588702
239 + 31588463 = 31588702
263 + 31588439 = 31588702

Showing the first eight; more decompositions exist.
