Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641370, here are decompositions:

19 + 8641351 = 8641370
43 + 8641327 = 8641370
61 + 8641309 = 8641370
97 + 8641273 = 8641370
139 + 8641231 = 8641370
223 + 8641147 = 8641370
277 + 8641093 = 8641370
307 + 8641063 = 8641370

Showing the first eight; more decompositions exist.
