Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548726, here are decompositions:

29 + 31548697 = 31548726
67 + 31548659 = 31548726
73 + 31548653 = 31548726
107 + 31548619 = 31548726
113 + 31548613 = 31548726
149 + 31548577 = 31548726
163 + 31548563 = 31548726
179 + 31548547 = 31548726

Showing the first eight; more decompositions exist.
