Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641424, here are decompositions:

3 + 8641421 = 8641424
73 + 8641351 = 8641424
97 + 8641327 = 8641424
151 + 8641273 = 8641424
193 + 8641231 = 8641424
277 + 8641147 = 8641424
331 + 8641093 = 8641424
457 + 8640967 = 8641424

Showing the first eight; more decompositions exist.
