Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530376, here are decompositions:

29 + 31530347 = 31530376
83 + 31530293 = 31530376
107 + 31530269 = 31530376
173 + 31530203 = 31530376
179 + 31530197 = 31530376
233 + 31530143 = 31530376
347 + 31530029 = 31530376
359 + 31530017 = 31530376

Showing the first eight; more decompositions exist.
