Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31511674, here are decompositions:

23 + 31511651 = 31511674
137 + 31511537 = 31511674
191 + 31511483 = 31511674
197 + 31511477 = 31511674
251 + 31511423 = 31511674
347 + 31511327 = 31511674
353 + 31511321 = 31511674
443 + 31511231 = 31511674

Showing the first eight; more decompositions exist.
