Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551594, here are decompositions:

7 + 31551587 = 31551594
17 + 31551577 = 31551594
47 + 31551547 = 31551594
97 + 31551497 = 31551594
157 + 31551437 = 31551594
163 + 31551431 = 31551594
181 + 31551413 = 31551594
233 + 31551361 = 31551594

Showing the first eight; more decompositions exist.
