Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543998, here are decompositions:

7 + 31543991 = 31543998
11 + 31543987 = 31543998
19 + 31543979 = 31543998
37 + 31543961 = 31543998
71 + 31543927 = 31543998
127 + 31543871 = 31543998
139 + 31543859 = 31543998
151 + 31543847 = 31543998

Showing the first eight; more decompositions exist.
