Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543448, here are decompositions:

19 + 31543429 = 31543448
229 + 31543219 = 31543448
241 + 31543207 = 31543448
379 + 31543069 = 31543448
439 + 31543009 = 31543448
457 + 31542991 = 31543448
499 + 31542949 = 31543448
571 + 31542877 = 31543448

Showing the first eight; more decompositions exist.
