Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552822, here are decompositions:

5 + 31552817 = 31552822
89 + 31552733 = 31552822
101 + 31552721 = 31552822
113 + 31552709 = 31552822
179 + 31552643 = 31552822
233 + 31552589 = 31552822
269 + 31552553 = 31552822
401 + 31552421 = 31552822

Showing the first eight; more decompositions exist.
