Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626676, here are decompositions:

113 + 31626563 = 31626676
239 + 31626437 = 31626676
269 + 31626407 = 31626676
293 + 31626383 = 31626676
317 + 31626359 = 31626676
353 + 31626323 = 31626676
443 + 31626233 = 31626676
467 + 31626209 = 31626676

Showing the first eight; more decompositions exist.
