Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31876, here are decompositions:

3 + 31873 = 31876
17 + 31859 = 31876
29 + 31847 = 31876
59 + 31817 = 31876
83 + 31793 = 31876
107 + 31769 = 31876
149 + 31727 = 31876
227 + 31649 = 31876

Showing the first eight; more decompositions exist.
