Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543326, here are decompositions:

53 + 31543273 = 31543326
83 + 31543243 = 31543326
103 + 31543223 = 31543326
107 + 31543219 = 31543326
109 + 31543217 = 31543326
163 + 31543163 = 31543326
193 + 31543133 = 31543326
223 + 31543103 = 31543326

Showing the first eight; more decompositions exist.
