Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524486, here are decompositions:

17 + 31524469 = 31524486
67 + 31524419 = 31524486
83 + 31524403 = 31524486
193 + 31524293 = 31524486
229 + 31524257 = 31524486
263 + 31524223 = 31524486
293 + 31524193 = 31524486
353 + 31524133 = 31524486

Showing the first eight; more decompositions exist.
