Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641172, here are decompositions:

79 + 8641093 = 8641172
109 + 8641063 = 8641172
223 + 8640949 = 8641172
283 + 8640889 = 8641172
313 + 8640859 = 8641172
349 + 8640823 = 8641172
373 + 8640799 = 8641172
433 + 8640739 = 8641172

Showing the first eight; more decompositions exist.
