Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543482, here are decompositions:

29 + 31543453 = 31543482
31 + 31543451 = 31543482
53 + 31543429 = 31543482
151 + 31543331 = 31543482
181 + 31543301 = 31543482
239 + 31543243 = 31543482
251 + 31543231 = 31543482
263 + 31543219 = 31543482

Showing the first eight; more decompositions exist.
