Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622354, here are decompositions:

7 + 31622347 = 31622354
61 + 31622293 = 31622354
67 + 31622287 = 31622354
73 + 31622281 = 31622354
97 + 31622257 = 31622354
223 + 31622131 = 31622354
241 + 31622113 = 31622354
307 + 31622047 = 31622354

Showing the first eight; more decompositions exist.
