Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618870, here are decompositions:

3 + 8618867 = 8618870
19 + 8618851 = 8618870
37 + 8618833 = 8618870
61 + 8618809 = 8618870
181 + 8618689 = 8618870
277 + 8618593 = 8618870
313 + 8618557 = 8618870
457 + 8618413 = 8618870

Showing the first eight; more decompositions exist.
