Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626554, here are decompositions:

7 + 31626547 = 31626554
61 + 31626493 = 31626554
73 + 31626481 = 31626554
307 + 31626247 = 31626554
601 + 31625953 = 31626554
643 + 31625911 = 31626554
733 + 31625821 = 31626554
787 + 31625767 = 31626554

Showing the first eight; more decompositions exist.
