Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641374, here are decompositions:

13 + 8641361 = 8641374
23 + 8641351 = 8641374
43 + 8641331 = 8641374
47 + 8641327 = 8641374
73 + 8641301 = 8641374
101 + 8641273 = 8641374
127 + 8641247 = 8641374
163 + 8641211 = 8641374

Showing the first eight; more decompositions exist.
