Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548766, here are decompositions:

3 + 31548763 = 31548766
17 + 31548749 = 31548766
23 + 31548743 = 31548766
89 + 31548677 = 31548766
107 + 31548659 = 31548766
113 + 31548653 = 31548766
173 + 31548593 = 31548766
233 + 31548533 = 31548766

Showing the first eight; more decompositions exist.
