Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294987770, here are decompositions:

13 + 4294987757 = 4294987770
19 + 4294987751 = 4294987770
67 + 4294987703 = 4294987770
89 + 4294987681 = 4294987770
149 + 4294987621 = 4294987770
163 + 4294987607 = 4294987770
181 + 4294987589 = 4294987770
191 + 4294987579 = 4294987770

Showing the first eight; more decompositions exist.
