Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543266, here are decompositions:

23 + 31543243 = 31543266
43 + 31543223 = 31543266
47 + 31543219 = 31543266
59 + 31543207 = 31543266
103 + 31543163 = 31543266
163 + 31543103 = 31543266
197 + 31543069 = 31543266
199 + 31543067 = 31543266

Showing the first eight; more decompositions exist.
