Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648222, here are decompositions:

31 + 8648191 = 8648222
43 + 8648179 = 8648222
73 + 8648149 = 8648222
109 + 8648113 = 8648222
139 + 8648083 = 8648222
229 + 8647993 = 8648222
421 + 8647801 = 8648222
439 + 8647783 = 8648222

Showing the first eight; more decompositions exist.
