Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548026, here are decompositions:

19 + 31548007 = 31548026
67 + 31547959 = 31548026
73 + 31547953 = 31548026
109 + 31547917 = 31548026
193 + 31547833 = 31548026
277 + 31547749 = 31548026
397 + 31547629 = 31548026
409 + 31547617 = 31548026

Showing the first eight; more decompositions exist.
