Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542996, here are decompositions:

5 + 31542991 = 31542996
29 + 31542967 = 31542996
47 + 31542949 = 31542996
53 + 31542943 = 31542996
59 + 31542937 = 31542996
139 + 31542857 = 31542996
167 + 31542829 = 31542996
197 + 31542799 = 31542996

Showing the first eight; more decompositions exist.
