Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559548, here are decompositions:

11 + 31559537 = 31559548
47 + 31559501 = 31559548
101 + 31559447 = 31559548
131 + 31559417 = 31559548
197 + 31559351 = 31559548
227 + 31559321 = 31559548
359 + 31559189 = 31559548
467 + 31559081 = 31559548

Showing the first eight; more decompositions exist.
