Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640254, here are decompositions:

3 + 8640251 = 8640254
13 + 8640241 = 8640254
43 + 8640211 = 8640254
67 + 8640187 = 8640254
241 + 8640013 = 8640254
277 + 8639977 = 8640254
331 + 8639923 = 8640254
457 + 8639797 = 8640254

Showing the first eight; more decompositions exist.
