Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543370, here are decompositions:

97 + 31543273 = 31543370
127 + 31543243 = 31543370
139 + 31543231 = 31543370
151 + 31543219 = 31543370
163 + 31543207 = 31543370
379 + 31542991 = 31543370
421 + 31542949 = 31543370
433 + 31542937 = 31543370

Showing the first eight; more decompositions exist.
