Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640734, here are decompositions:

31 + 8640703 = 8640734
43 + 8640691 = 8640734
181 + 8640553 = 8640734
241 + 8640493 = 8640734
283 + 8640451 = 8640734
307 + 8640427 = 8640734
397 + 8640337 = 8640734
523 + 8640211 = 8640734

Showing the first eight; more decompositions exist.
