Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543892, here are decompositions:

19 + 31543873 = 31543892
109 + 31543783 = 31543892
181 + 31543711 = 31543892
223 + 31543669 = 31543892
313 + 31543579 = 31543892
349 + 31543543 = 31543892
439 + 31543453 = 31543892
463 + 31543429 = 31543892

Showing the first eight; more decompositions exist.
