Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548794, here are decompositions:

31 + 31548763 = 31548794
37 + 31548757 = 31548794
61 + 31548733 = 31548794
97 + 31548697 = 31548794
181 + 31548613 = 31548794
367 + 31548427 = 31548794
463 + 31548331 = 31548794
661 + 31548133 = 31548794

Showing the first eight; more decompositions exist.
