Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648636, here are decompositions:

79 + 8648557 = 8648636
103 + 8648533 = 8648636
223 + 8648413 = 8648636
313 + 8648323 = 8648636
397 + 8648239 = 8648636
457 + 8648179 = 8648636
487 + 8648149 = 8648636
523 + 8648113 = 8648636

Showing the first eight; more decompositions exist.
