Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978220, here are decompositions:

19 + 4294978201 = 4294978220
73 + 4294978147 = 4294978220
97 + 4294978123 = 4294978220
139 + 4294978081 = 4294978220
163 + 4294978057 = 4294978220
193 + 4294978027 = 4294978220
199 + 4294978021 = 4294978220
229 + 4294977991 = 4294978220

Showing the first eight; more decompositions exist.
