Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648398, here are decompositions:

29 + 8648369 = 8648398
131 + 8648267 = 8648398
401 + 8647997 = 8648398
419 + 8647979 = 8648398
431 + 8647967 = 8648398
449 + 8647949 = 8648398
461 + 8647937 = 8648398
509 + 8647889 = 8648398

Showing the first eight; more decompositions exist.
