Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609240, here are decompositions:

67 + 8609173 = 8609240
103 + 8609137 = 8609240
163 + 8609077 = 8609240
331 + 8608909 = 8609240
349 + 8608891 = 8609240
379 + 8608861 = 8609240
439 + 8608801 = 8609240
463 + 8608777 = 8609240

Showing the first eight; more decompositions exist.
