Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648540, here are decompositions:

3 + 8648537 = 8648540
7 + 8648533 = 8648540
127 + 8648413 = 8648540
151 + 8648389 = 8648540
193 + 8648347 = 8648540
223 + 8648317 = 8648540
349 + 8648191 = 8648540
409 + 8648131 = 8648540

Showing the first eight; more decompositions exist.
