Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542036, here are decompositions:

5 + 31542031 = 31542036
13 + 31542023 = 31542036
23 + 31542013 = 31542036
47 + 31541989 = 31542036
59 + 31541977 = 31542036
103 + 31541933 = 31542036
137 + 31541899 = 31542036
167 + 31541869 = 31542036

Showing the first eight; more decompositions exist.
