Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599346, here are decompositions:

5 + 31599341 = 31599346
173 + 31599173 = 31599346
419 + 31598927 = 31599346
479 + 31598867 = 31599346
557 + 31598789 = 31599346
563 + 31598783 = 31599346
593 + 31598753 = 31599346
659 + 31598687 = 31599346

Showing the first eight; more decompositions exist.
