Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458298, here are decompositions:

59 + 31458239 = 31458298
101 + 31458197 = 31458298
107 + 31458191 = 31458298
167 + 31458131 = 31458298
449 + 31457849 = 31458298
467 + 31457831 = 31458298
479 + 31457819 = 31458298
569 + 31457729 = 31458298

Showing the first eight; more decompositions exist.
