Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524426, here are decompositions:

7 + 31524419 = 31524426
23 + 31524403 = 31524426
83 + 31524343 = 31524426
149 + 31524277 = 31524426
229 + 31524197 = 31524426
233 + 31524193 = 31524426
293 + 31524133 = 31524426
379 + 31524047 = 31524426

Showing the first eight; more decompositions exist.
