Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543674, here are decompositions:

5 + 31543669 = 31543674
13 + 31543661 = 31543674
31 + 31543643 = 31543674
103 + 31543571 = 31543674
131 + 31543543 = 31543674
193 + 31543481 = 31543674
223 + 31543451 = 31543674
277 + 31543397 = 31543674

Showing the first eight; more decompositions exist.
