Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626384, here are decompositions:

7 + 31626377 = 31626384
17 + 31626367 = 31626384
47 + 31626337 = 31626384
61 + 31626323 = 31626384
137 + 31626247 = 31626384
151 + 31626233 = 31626384
191 + 31626193 = 31626384
193 + 31626191 = 31626384

Showing the first eight; more decompositions exist.
