Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640546, here are decompositions:

43 + 8640503 = 8640546
53 + 8640493 = 8640546
107 + 8640439 = 8640546
127 + 8640419 = 8640546
137 + 8640409 = 8640546
139 + 8640407 = 8640546
197 + 8640349 = 8640546
283 + 8640263 = 8640546

Showing the first eight; more decompositions exist.
