Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648320, here are decompositions:

3 + 8648317 = 8648320
53 + 8648267 = 8648320
227 + 8648093 = 8648320
353 + 8647967 = 8648320
383 + 8647937 = 8648320
431 + 8647889 = 8648320
503 + 8647817 = 8648320
809 + 8647511 = 8648320

Showing the first eight; more decompositions exist.
