Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594068, here are decompositions:

5 + 31594063 = 31594068
7 + 31594061 = 31594068
19 + 31594049 = 31594068
29 + 31594039 = 31594068
109 + 31593959 = 31594068
131 + 31593937 = 31594068
137 + 31593931 = 31594068
167 + 31593901 = 31594068

Showing the first eight; more decompositions exist.
