Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542132, here are decompositions:

19 + 31542113 = 31542132
29 + 31542103 = 31542132
101 + 31542031 = 31542132
109 + 31542023 = 31542132
131 + 31542001 = 31542132
151 + 31541981 = 31542132
199 + 31541933 = 31542132
229 + 31541903 = 31542132

Showing the first eight; more decompositions exist.
