Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529448, here are decompositions:

17 + 31529431 = 31529448
89 + 31529359 = 31529448
101 + 31529347 = 31529448
127 + 31529321 = 31529448
179 + 31529269 = 31529448
191 + 31529257 = 31529448
199 + 31529249 = 31529448
229 + 31529219 = 31529448

Showing the first eight; more decompositions exist.
