Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599558, here are decompositions:

5 + 31599553 = 31599558
7 + 31599551 = 31599558
59 + 31599499 = 31599558
71 + 31599487 = 31599558
127 + 31599431 = 31599558
251 + 31599307 = 31599558
311 + 31599247 = 31599558
401 + 31599157 = 31599558

Showing the first eight; more decompositions exist.
