Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542102, here are decompositions:

19 + 31542083 = 31542102
71 + 31542031 = 31542102
79 + 31542023 = 31542102
89 + 31542013 = 31542102
101 + 31542001 = 31542102
113 + 31541989 = 31542102
131 + 31541971 = 31542102
199 + 31541903 = 31542102

Showing the first eight; more decompositions exist.
