Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641088, here are decompositions:

139 + 8640949 = 8641088
199 + 8640889 = 8641088
229 + 8640859 = 8641088
271 + 8640817 = 8641088
307 + 8640781 = 8641088
349 + 8640739 = 8641088
397 + 8640691 = 8641088
409 + 8640679 = 8641088

Showing the first eight; more decompositions exist.
