Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542060, here are decompositions:

23 + 31542037 = 31542060
29 + 31542031 = 31542060
37 + 31542023 = 31542060
47 + 31542013 = 31542060
59 + 31542001 = 31542060
71 + 31541989 = 31542060
79 + 31541981 = 31542060
83 + 31541977 = 31542060

Showing the first eight; more decompositions exist.
