Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482526, here are decompositions:

17 + 31482509 = 31482526
137 + 31482389 = 31482526
233 + 31482293 = 31482526
269 + 31482257 = 31482526
347 + 31482179 = 31482526
353 + 31482173 = 31482526
359 + 31482167 = 31482526
443 + 31482083 = 31482526

Showing the first eight; more decompositions exist.
