Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641670, here are decompositions:

19 + 8641651 = 8641670
67 + 8641603 = 8641670
127 + 8641543 = 8641670
151 + 8641519 = 8641670
157 + 8641513 = 8641670
199 + 8641471 = 8641670
241 + 8641429 = 8641670
397 + 8641273 = 8641670

Showing the first eight; more decompositions exist.
