Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627870, here are decompositions:

3 + 8627867 = 8627870
19 + 8627851 = 8627870
37 + 8627833 = 8627870
61 + 8627809 = 8627870
157 + 8627713 = 8627870
337 + 8627533 = 8627870
367 + 8627503 = 8627870
373 + 8627497 = 8627870

Showing the first eight; more decompositions exist.
