Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641232, here are decompositions:

139 + 8641093 = 8641232
283 + 8640949 = 8641232
349 + 8640883 = 8641232
373 + 8640859 = 8641232
409 + 8640823 = 8641232
433 + 8640799 = 8641232
499 + 8640733 = 8641232
541 + 8640691 = 8641232

Showing the first eight; more decompositions exist.
