Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548074, here are decompositions:

43 + 31548031 = 31548074
67 + 31548007 = 31548074
157 + 31547917 = 31548074
223 + 31547851 = 31548074
241 + 31547833 = 31548074
367 + 31547707 = 31548074
373 + 31547701 = 31548074
433 + 31547641 = 31548074

Showing the first eight; more decompositions exist.
