Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598876, here are decompositions:

3 + 31598873 = 31598876
13 + 31598863 = 31598876
19 + 31598857 = 31598876
37 + 31598839 = 31598876
97 + 31598779 = 31598876
193 + 31598683 = 31598876
229 + 31598647 = 31598876
457 + 31598419 = 31598876

Showing the first eight; more decompositions exist.
