Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972980, here are decompositions:

29 + 4294972951 = 4294972980
83 + 4294972897 = 4294972980
113 + 4294972867 = 4294972980
157 + 4294972823 = 4294972980
173 + 4294972807 = 4294972980
191 + 4294972789 = 4294972980
229 + 4294972751 = 4294972980
317 + 4294972663 = 4294972980

Showing the first eight; more decompositions exist.
