Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543144, here are decompositions:

11 + 31543133 = 31543144
41 + 31543103 = 31543144
173 + 31542971 = 31543144
233 + 31542911 = 31543144
263 + 31542881 = 31543144
317 + 31542827 = 31543144
467 + 31542677 = 31543144
557 + 31542587 = 31543144

Showing the first eight; more decompositions exist.
