Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641462, here are decompositions:

29 + 8641433 = 8641462
41 + 8641421 = 8641462
101 + 8641361 = 8641462
113 + 8641349 = 8641462
131 + 8641331 = 8641462
173 + 8641289 = 8641462
251 + 8641211 = 8641462
383 + 8641079 = 8641462

Showing the first eight; more decompositions exist.
