Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548530, here are decompositions:

3 + 31548527 = 31548530
31 + 31548499 = 31548530
103 + 31548427 = 31548530
199 + 31548331 = 31548530
229 + 31548301 = 31548530
397 + 31548133 = 31548530
421 + 31548109 = 31548530
499 + 31548031 = 31548530

Showing the first eight; more decompositions exist.
