Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626326, here are decompositions:

3 + 31626323 = 31626326
79 + 31626247 = 31626326
97 + 31626229 = 31626326
307 + 31626019 = 31626326
373 + 31625953 = 31626326
409 + 31625917 = 31626326
547 + 31625779 = 31626326
673 + 31625653 = 31626326

Showing the first eight; more decompositions exist.
