Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543314, here are decompositions:

13 + 31543301 = 31543314
41 + 31543273 = 31543314
71 + 31543243 = 31543314
83 + 31543231 = 31543314
97 + 31543217 = 31543314
107 + 31543207 = 31543314
151 + 31543163 = 31543314
181 + 31543133 = 31543314

Showing the first eight; more decompositions exist.
