Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641392, here are decompositions:

31 + 8641361 = 8641392
41 + 8641351 = 8641392
43 + 8641349 = 8641392
61 + 8641331 = 8641392
73 + 8641319 = 8641392
83 + 8641309 = 8641392
103 + 8641289 = 8641392
181 + 8641211 = 8641392

Showing the first eight; more decompositions exist.
