Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644070, here are decompositions:

13 + 8644057 = 8644070
73 + 8643997 = 8644070
79 + 8643991 = 8644070
151 + 8643919 = 8644070
181 + 8643889 = 8644070
283 + 8643787 = 8644070
313 + 8643757 = 8644070
349 + 8643721 = 8644070

Showing the first eight; more decompositions exist.
