Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737870, here are decompositions:

3 + 8737867 = 8737870
41 + 8737829 = 8737870
107 + 8737763 = 8737870
173 + 8737697 = 8737870
293 + 8737577 = 8737870
347 + 8737523 = 8737870
389 + 8737481 = 8737870
443 + 8737427 = 8737870

Showing the first eight; more decompositions exist.
