Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626766, here are decompositions:

233 + 31626533 = 31626766
359 + 31626407 = 31626766
383 + 31626383 = 31626766
389 + 31626377 = 31626766
443 + 31626323 = 31626766
557 + 31626209 = 31626766
569 + 31626197 = 31626766
599 + 31626167 = 31626766

Showing the first eight; more decompositions exist.
