Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640992, here are decompositions:

43 + 8640949 = 8640992
103 + 8640889 = 8640992
109 + 8640883 = 8640992
193 + 8640799 = 8640992
211 + 8640781 = 8640992
313 + 8640679 = 8640992
433 + 8640559 = 8640992
439 + 8640553 = 8640992

Showing the first eight; more decompositions exist.
