Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543382, here are decompositions:

109 + 31543273 = 31543382
139 + 31543243 = 31543382
151 + 31543231 = 31543382
163 + 31543219 = 31543382
313 + 31543069 = 31543382
373 + 31543009 = 31543382
433 + 31542949 = 31543382
439 + 31542943 = 31543382

Showing the first eight; more decompositions exist.
