Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533438, here are decompositions:

7 + 31533431 = 31533438
29 + 31533409 = 31533438
59 + 31533379 = 31533438
67 + 31533371 = 31533438
179 + 31533259 = 31533438
229 + 31533209 = 31533438
271 + 31533167 = 31533438
311 + 31533127 = 31533438

Showing the first eight; more decompositions exist.
