Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641402, here are decompositions:

41 + 8641361 = 8641402
53 + 8641349 = 8641402
71 + 8641331 = 8641402
83 + 8641319 = 8641402
101 + 8641301 = 8641402
113 + 8641289 = 8641402
191 + 8641211 = 8641402
269 + 8641133 = 8641402

Showing the first eight; more decompositions exist.
