Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978120, here are decompositions:

29 + 4294978091 = 4294978120
53 + 4294978067 = 4294978120
131 + 4294977989 = 4294978120
227 + 4294977893 = 4294978120
239 + 4294977881 = 4294978120
281 + 4294977839 = 4294978120
359 + 4294977761 = 4294978120
449 + 4294977671 = 4294978120

Showing the first eight; more decompositions exist.
