Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598788, here are decompositions:

5 + 31598783 = 31598788
17 + 31598771 = 31598788
71 + 31598717 = 31598788
101 + 31598687 = 31598788
197 + 31598591 = 31598788
251 + 31598537 = 31598788
269 + 31598519 = 31598788
461 + 31598327 = 31598788

Showing the first eight; more decompositions exist.
