Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542108, here are decompositions:

5 + 31542103 = 31542108
41 + 31542067 = 31542108
71 + 31542037 = 31542108
97 + 31542011 = 31542108
107 + 31542001 = 31542108
127 + 31541981 = 31542108
131 + 31541977 = 31542108
137 + 31541971 = 31542108

Showing the first eight; more decompositions exist.
