Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548370, here are decompositions:

47 + 31548323 = 31548370
71 + 31548299 = 31548370
83 + 31548287 = 31548370
89 + 31548281 = 31548370
101 + 31548269 = 31548370
107 + 31548263 = 31548370
353 + 31548017 = 31548370
389 + 31547981 = 31548370

Showing the first eight; more decompositions exist.
