Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538424, here are decompositions:

13 + 31538411 = 31538424
17 + 31538407 = 31538424
53 + 31538371 = 31538424
97 + 31538327 = 31538424
163 + 31538261 = 31538424
173 + 31538251 = 31538424
263 + 31538161 = 31538424
271 + 31538153 = 31538424

Showing the first eight; more decompositions exist.
