Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543074, here are decompositions:

5 + 31543069 = 31543074
7 + 31543067 = 31543074
83 + 31542991 = 31543074
103 + 31542971 = 31543074
107 + 31542967 = 31543074
131 + 31542943 = 31543074
137 + 31542937 = 31543074
163 + 31542911 = 31543074

Showing the first eight; more decompositions exist.
