Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294973780, here are decompositions:

37 + 4294973743 = 4294973780
67 + 4294973713 = 4294973780
109 + 4294973671 = 4294973780
151 + 4294973629 = 4294973780
193 + 4294973587 = 4294973780
211 + 4294973569 = 4294973780
241 + 4294973539 = 4294973780
283 + 4294973497 = 4294973780

Showing the first eight; more decompositions exist.
