Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498504, here are decompositions:

5 + 31498499 = 31498504
41 + 31498463 = 31498504
83 + 31498421 = 31498504
137 + 31498367 = 31498504
197 + 31498307 = 31498504
227 + 31498277 = 31498504
251 + 31498253 = 31498504
311 + 31498193 = 31498504

Showing the first eight; more decompositions exist.
