Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563374, here are decompositions:

97 + 31563277 = 31563374
181 + 31563193 = 31563374
211 + 31563163 = 31563374
331 + 31563043 = 31563374
373 + 31563001 = 31563374
457 + 31562917 = 31563374
463 + 31562911 = 31563374
547 + 31562827 = 31563374

Showing the first eight; more decompositions exist.
