Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542110, here are decompositions:

7 + 31542103 = 31542110
43 + 31542067 = 31542110
73 + 31542037 = 31542110
79 + 31542031 = 31542110
97 + 31542013 = 31542110
109 + 31542001 = 31542110
139 + 31541971 = 31542110
211 + 31541899 = 31542110

Showing the first eight; more decompositions exist.
