Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510834, here are decompositions:

23 + 31510811 = 31510834
53 + 31510781 = 31510834
71 + 31510763 = 31510834
281 + 31510553 = 31510834
293 + 31510541 = 31510834
317 + 31510517 = 31510834
347 + 31510487 = 31510834
401 + 31510433 = 31510834

Showing the first eight; more decompositions exist.
