Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294987020, here are decompositions:

29 + 4294986991 = 4294987020
31 + 4294986989 = 4294987020
53 + 4294986967 = 4294987020
61 + 4294986959 = 4294987020
67 + 4294986953 = 4294987020
109 + 4294986911 = 4294987020
113 + 4294986907 = 4294987020
127 + 4294986893 = 4294987020

Showing the first eight; more decompositions exist.
