Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543524, here are decompositions:

43 + 31543481 = 31543524
71 + 31543453 = 31543524
73 + 31543451 = 31543524
127 + 31543397 = 31543524
163 + 31543361 = 31543524
193 + 31543331 = 31543524
223 + 31543301 = 31543524
251 + 31543273 = 31543524

Showing the first eight; more decompositions exist.
