Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640848, here are decompositions:

31 + 8640817 = 8640848
61 + 8640787 = 8640848
67 + 8640781 = 8640848
109 + 8640739 = 8640848
157 + 8640691 = 8640848
367 + 8640481 = 8640848
397 + 8640451 = 8640848
409 + 8640439 = 8640848

Showing the first eight; more decompositions exist.
