Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542096, here are decompositions:

13 + 31542083 = 31542096
29 + 31542067 = 31542096
59 + 31542037 = 31542096
73 + 31542023 = 31542096
83 + 31542013 = 31542096
107 + 31541989 = 31542096
163 + 31541933 = 31542096
193 + 31541903 = 31542096

Showing the first eight; more decompositions exist.
