Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548948, here are decompositions:

131 + 31548817 = 31548948
181 + 31548767 = 31548948
191 + 31548757 = 31548948
199 + 31548749 = 31548948
251 + 31548697 = 31548948
271 + 31548677 = 31548948
307 + 31548641 = 31548948
397 + 31548551 = 31548948

Showing the first eight; more decompositions exist.
