Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462298, here are decompositions:

31 + 31462267 = 31462298
157 + 31462141 = 31462298
229 + 31462069 = 31462298
277 + 31462021 = 31462298
337 + 31461961 = 31462298
349 + 31461949 = 31462298
379 + 31461919 = 31462298
457 + 31461841 = 31462298

Showing the first eight; more decompositions exist.
