Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594876, here are decompositions:

3 + 31594873 = 31594876
107 + 31594769 = 31594876
149 + 31594727 = 31594876
263 + 31594613 = 31594876
293 + 31594583 = 31594876
503 + 31594373 = 31594876
683 + 31594193 = 31594876
743 + 31594133 = 31594876

Showing the first eight; more decompositions exist.
