Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543298, here are decompositions:

67 + 31543231 = 31543298
79 + 31543219 = 31543298
229 + 31543069 = 31543298
307 + 31542991 = 31543298
331 + 31542967 = 31543298
349 + 31542949 = 31543298
421 + 31542877 = 31543298
487 + 31542811 = 31543298

Showing the first eight; more decompositions exist.
