Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548350, here are decompositions:

7 + 31548343 = 31548350
19 + 31548331 = 31548350
37 + 31548313 = 31548350
241 + 31548109 = 31548350
271 + 31548079 = 31548350
397 + 31547953 = 31548350
433 + 31547917 = 31548350
499 + 31547851 = 31548350

Showing the first eight; more decompositions exist.
