Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640482, here are decompositions:

31 + 8640451 = 8640482
43 + 8640439 = 8640482
73 + 8640409 = 8640482
223 + 8640259 = 8640482
241 + 8640241 = 8640482
271 + 8640211 = 8640482
313 + 8640169 = 8640482
349 + 8640133 = 8640482

Showing the first eight; more decompositions exist.
