Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548122, here are decompositions:

13 + 31548109 = 31548122
19 + 31548103 = 31548122
43 + 31548079 = 31548122
163 + 31547959 = 31548122
271 + 31547851 = 31548122
283 + 31547839 = 31548122
373 + 31547749 = 31548122
421 + 31547701 = 31548122

Showing the first eight; more decompositions exist.
