Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548030, here are decompositions:

13 + 31548017 = 31548030
23 + 31548007 = 31548030
37 + 31547993 = 31548030
71 + 31547959 = 31548030
97 + 31547933 = 31548030
109 + 31547921 = 31548030
113 + 31547917 = 31548030
179 + 31547851 = 31548030

Showing the first eight; more decompositions exist.
