Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543062, here are decompositions:

43 + 31543019 = 31543062
53 + 31543009 = 31543062
71 + 31542991 = 31543062
113 + 31542949 = 31543062
151 + 31542911 = 31543062
181 + 31542881 = 31543062
233 + 31542829 = 31543062
251 + 31542811 = 31543062

Showing the first eight; more decompositions exist.
