Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548524, here are decompositions:

3 + 31548521 = 31548524
97 + 31548427 = 31548524
181 + 31548343 = 31548524
193 + 31548331 = 31548524
211 + 31548313 = 31548524
223 + 31548301 = 31548524
421 + 31548103 = 31548524
571 + 31547953 = 31548524

Showing the first eight; more decompositions exist.
