Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648430, here are decompositions:

17 + 8648413 = 8648430
41 + 8648389 = 8648430
59 + 8648371 = 8648430
61 + 8648369 = 8648430
83 + 8648347 = 8648430
97 + 8648333 = 8648430
107 + 8648323 = 8648430
113 + 8648317 = 8648430

Showing the first eight; more decompositions exist.
