Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542056, here are decompositions:

19 + 31542037 = 31542056
43 + 31542013 = 31542056
67 + 31541989 = 31542056
79 + 31541977 = 31542056
157 + 31541899 = 31542056
163 + 31541893 = 31542056
199 + 31541857 = 31542056
229 + 31541827 = 31542056

Showing the first eight; more decompositions exist.
