Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626824, here are decompositions:

37 + 31626787 = 31626824
157 + 31626667 = 31626824
277 + 31626547 = 31626824
331 + 31626493 = 31626824
457 + 31626367 = 31626824
487 + 31626337 = 31626824
577 + 31626247 = 31626824
631 + 31626193 = 31626824

Showing the first eight; more decompositions exist.
