Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294997220, here are decompositions:

23 + 4294997197 = 4294997220
29 + 4294997191 = 4294997220
47 + 4294997173 = 4294997220
61 + 4294997159 = 4294997220
71 + 4294997149 = 4294997220
79 + 4294997141 = 4294997220
89 + 4294997131 = 4294997220
97 + 4294997123 = 4294997220

Showing the first eight; more decompositions exist.
