Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593398, here are decompositions:

7 + 31593391 = 31593398
367 + 31593031 = 31593398
439 + 31592959 = 31593398
601 + 31592797 = 31593398
619 + 31592779 = 31593398
757 + 31592641 = 31593398
1009 + 31592389 = 31593398
1021 + 31592377 = 31593398

Showing the first eight; more decompositions exist.
