Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294956978, here are decompositions:

29 + 4294956949 = 4294956978
41 + 4294956937 = 4294956978
89 + 4294956889 = 4294956978
97 + 4294956881 = 4294956978
131 + 4294956847 = 4294956978
139 + 4294956839 = 4294956978
149 + 4294956829 = 4294956978
227 + 4294956751 = 4294956978

Showing the first eight; more decompositions exist.
