Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523766, here are decompositions:

5 + 31523761 = 31523766
13 + 31523753 = 31523766
17 + 31523749 = 31523766
59 + 31523707 = 31523766
97 + 31523669 = 31523766
107 + 31523659 = 31523766
167 + 31523599 = 31523766
227 + 31523539 = 31523766

Showing the first eight; more decompositions exist.
