Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498726, here are decompositions:

23 + 31498703 = 31498726
167 + 31498559 = 31498726
179 + 31498547 = 31498726
197 + 31498529 = 31498726
227 + 31498499 = 31498726
257 + 31498469 = 31498726
263 + 31498463 = 31498726
359 + 31498367 = 31498726

Showing the first eight; more decompositions exist.
