Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527298, here are decompositions:

107 + 31527191 = 31527298
149 + 31527149 = 31527298
167 + 31527131 = 31527298
191 + 31527107 = 31527298
251 + 31527047 = 31527298
281 + 31527017 = 31527298
359 + 31526939 = 31527298
419 + 31526879 = 31527298

Showing the first eight; more decompositions exist.
