Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542068, here are decompositions:

31 + 31542037 = 31542068
37 + 31542031 = 31542068
67 + 31542001 = 31542068
79 + 31541989 = 31542068
97 + 31541971 = 31542068
199 + 31541869 = 31542068
211 + 31541857 = 31542068
241 + 31541827 = 31542068

Showing the first eight; more decompositions exist.
