Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542954, here are decompositions:

5 + 31542949 = 31542954
11 + 31542943 = 31542954
13 + 31542941 = 31542954
17 + 31542937 = 31542954
43 + 31542911 = 31542954
73 + 31542881 = 31542954
97 + 31542857 = 31542954
127 + 31542827 = 31542954

Showing the first eight; more decompositions exist.
