Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543692, here are decompositions:

23 + 31543669 = 31543692
31 + 31543661 = 31543692
113 + 31543579 = 31543692
149 + 31543543 = 31543692
163 + 31543529 = 31543692
211 + 31543481 = 31543692
239 + 31543453 = 31543692
241 + 31543451 = 31543692

Showing the first eight; more decompositions exist.
