Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626926, here are decompositions:

43 + 31626883 = 31626926
139 + 31626787 = 31626926
307 + 31626619 = 31626926
337 + 31626589 = 31626926
379 + 31626547 = 31626926
433 + 31626493 = 31626926
733 + 31626193 = 31626926
853 + 31626073 = 31626926

Showing the first eight; more decompositions exist.
