Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542026, here are decompositions:

3 + 31542023 = 31542026
13 + 31542013 = 31542026
37 + 31541989 = 31542026
127 + 31541899 = 31542026
157 + 31541869 = 31542026
199 + 31541827 = 31542026
349 + 31541677 = 31542026
367 + 31541659 = 31542026

Showing the first eight; more decompositions exist.
