Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543026, here are decompositions:

7 + 31543019 = 31543026
17 + 31543009 = 31543026
59 + 31542967 = 31543026
83 + 31542943 = 31543026
89 + 31542937 = 31543026
149 + 31542877 = 31543026
197 + 31542829 = 31543026
199 + 31542827 = 31543026

Showing the first eight; more decompositions exist.
