Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534298, here are decompositions:

67 + 31534231 = 31534298
157 + 31534141 = 31534298
181 + 31534117 = 31534298
241 + 31534057 = 31534298
331 + 31533967 = 31534298
349 + 31533949 = 31534298
379 + 31533919 = 31534298
577 + 31533721 = 31534298

Showing the first eight; more decompositions exist.
