Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626826, here are decompositions:

29 + 31626797 = 31626826
59 + 31626767 = 31626826
137 + 31626689 = 31626826
263 + 31626563 = 31626826
269 + 31626557 = 31626826
293 + 31626533 = 31626826
389 + 31626437 = 31626826
419 + 31626407 = 31626826

Showing the first eight; more decompositions exist.
