Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548756, here are decompositions:

7 + 31548749 = 31548756
13 + 31548743 = 31548756
17 + 31548739 = 31548756
23 + 31548733 = 31548756
59 + 31548697 = 31548756
79 + 31548677 = 31548756
97 + 31548659 = 31548756
103 + 31548653 = 31548756

Showing the first eight; more decompositions exist.
