Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543584, here are decompositions:

5 + 31543579 = 31543584
13 + 31543571 = 31543584
41 + 31543543 = 31543584
53 + 31543531 = 31543584
103 + 31543481 = 31543584
131 + 31543453 = 31543584
223 + 31543361 = 31543584
283 + 31543301 = 31543584

Showing the first eight; more decompositions exist.
