Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534548, here are decompositions:

5 + 31534543 = 31534548
47 + 31534501 = 31534548
61 + 31534487 = 31534548
107 + 31534441 = 31534548
137 + 31534411 = 31534548
179 + 31534369 = 31534548
251 + 31534297 = 31534548
277 + 31534271 = 31534548

Showing the first eight; more decompositions exist.
