Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4295072988, here are decompositions:

7 + 4295072981 = 4295072988
109 + 4295072879 = 4295072988
127 + 4295072861 = 4295072988
131 + 4295072857 = 4295072988
179 + 4295072809 = 4295072988
181 + 4295072807 = 4295072988
307 + 4295072681 = 4295072988
379 + 4295072609 = 4295072988

Showing the first eight; more decompositions exist.
