Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654240, here are decompositions:

3 + 8654237 = 8654240
19 + 8654221 = 8654240
151 + 8654089 = 8654240
193 + 8654047 = 8654240
211 + 8654029 = 8654240
223 + 8654017 = 8654240
229 + 8654011 = 8654240
277 + 8653963 = 8654240

Showing the first eight; more decompositions exist.
