Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294987980, here are decompositions:

29 + 4294987951 = 4294987980
61 + 4294987919 = 4294987980
131 + 4294987849 = 4294987980
181 + 4294987799 = 4294987980
211 + 4294987769 = 4294987980
223 + 4294987757 = 4294987980
229 + 4294987751 = 4294987980
277 + 4294987703 = 4294987980

Showing the first eight; more decompositions exist.
