Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527658, here are decompositions:

89 + 31527569 = 31527658
137 + 31527521 = 31527658
167 + 31527491 = 31527658
251 + 31527407 = 31527658
269 + 31527389 = 31527658
347 + 31527311 = 31527658
467 + 31527191 = 31527658
509 + 31527149 = 31527658

Showing the first eight; more decompositions exist.
