Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548958, here are decompositions:

5 + 31548953 = 31548958
101 + 31548857 = 31548958
191 + 31548767 = 31548958
281 + 31548677 = 31548958
317 + 31548641 = 31548958
431 + 31548527 = 31548958
491 + 31548467 = 31548958
557 + 31548401 = 31548958

Showing the first eight; more decompositions exist.
