Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543506, here are decompositions:

17 + 31543489 = 31543506
53 + 31543453 = 31543506
109 + 31543397 = 31543506
157 + 31543349 = 31543506
233 + 31543273 = 31543506
263 + 31543243 = 31543506
283 + 31543223 = 31543506
373 + 31543133 = 31543506

Showing the first eight; more decompositions exist.
