Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294987140, here are decompositions:

29 + 4294987111 = 4294987140
79 + 4294987061 = 4294987140
83 + 4294987057 = 4294987140
89 + 4294987051 = 4294987140
149 + 4294986991 = 4294987140
151 + 4294986989 = 4294987140
173 + 4294986967 = 4294987140
181 + 4294986959 = 4294987140

Showing the first eight; more decompositions exist.
