Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294995878, here are decompositions:

7 + 4294995871 = 4294995878
37 + 4294995841 = 4294995878
109 + 4294995769 = 4294995878
139 + 4294995739 = 4294995878
211 + 4294995667 = 4294995878
241 + 4294995637 = 4294995878
367 + 4294995511 = 4294995878
541 + 4294995337 = 4294995878

Showing the first eight; more decompositions exist.
