Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640296, here are decompositions:

37 + 8640259 = 8640296
109 + 8640187 = 8640296
127 + 8640169 = 8640296
163 + 8640133 = 8640296
283 + 8640013 = 8640296
373 + 8639923 = 8640296
397 + 8639899 = 8640296
433 + 8639863 = 8640296

Showing the first eight; more decompositions exist.
