Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294987188, here are decompositions:

31 + 4294987157 = 4294987188
47 + 4294987141 = 4294987188
127 + 4294987061 = 4294987188
131 + 4294987057 = 4294987188
137 + 4294987051 = 4294987188
197 + 4294986991 = 4294987188
199 + 4294986989 = 4294987188
229 + 4294986959 = 4294987188

Showing the first eight; more decompositions exist.
