Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541996, here are decompositions:

7 + 31541989 = 31541996
19 + 31541977 = 31541996
97 + 31541899 = 31541996
103 + 31541893 = 31541996
127 + 31541869 = 31541996
139 + 31541857 = 31541996
337 + 31541659 = 31541996
433 + 31541563 = 31541996

Showing the first eight; more decompositions exist.
