Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543982, here are decompositions:

3 + 31543979 = 31543982
79 + 31543903 = 31543982
109 + 31543873 = 31543982
139 + 31543843 = 31543982
199 + 31543783 = 31543982
271 + 31543711 = 31543982
313 + 31543669 = 31543982
439 + 31543543 = 31543982

Showing the first eight; more decompositions exist.
