Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626658, here are decompositions:

101 + 31626557 = 31626658
197 + 31626461 = 31626658
251 + 31626407 = 31626658
269 + 31626389 = 31626658
281 + 31626377 = 31626658
449 + 31626209 = 31626658
461 + 31626197 = 31626658
467 + 31626191 = 31626658

Showing the first eight; more decompositions exist.
