Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500376, here are decompositions:

23 + 31500353 = 31500376
113 + 31500263 = 31500376
179 + 31500197 = 31500376
227 + 31500149 = 31500376
263 + 31500113 = 31500376
269 + 31500107 = 31500376
293 + 31500083 = 31500376
353 + 31500023 = 31500376

Showing the first eight; more decompositions exist.
