Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294976820, here are decompositions:

23 + 4294976797 = 4294976820
47 + 4294976773 = 4294976820
89 + 4294976731 = 4294976820
97 + 4294976723 = 4294976820
103 + 4294976717 = 4294976820
181 + 4294976639 = 4294976820
193 + 4294976627 = 4294976820
241 + 4294976579 = 4294976820

Showing the first eight; more decompositions exist.
