Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648408, here are decompositions:

19 + 8648389 = 8648408
37 + 8648371 = 8648408
61 + 8648347 = 8648408
157 + 8648251 = 8648408
229 + 8648179 = 8648408
277 + 8648131 = 8648408
607 + 8647801 = 8648408
709 + 8647699 = 8648408

Showing the first eight; more decompositions exist.
