Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31068, here are decompositions:

5 + 31063 = 31068
17 + 31051 = 31068
29 + 31039 = 31068
97 + 30971 = 31068
127 + 30941 = 31068
131 + 30937 = 31068
137 + 30931 = 31068
157 + 30911 = 31068

Showing the first eight; more decompositions exist.
