Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640710, here are decompositions:

3 + 8640707 = 8640710
7 + 8640703 = 8640710
19 + 8640691 = 8640710
31 + 8640679 = 8640710
109 + 8640601 = 8640710
151 + 8640559 = 8640710
157 + 8640553 = 8640710
163 + 8640547 = 8640710

Showing the first eight; more decompositions exist.
