Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972780, here are decompositions:

29 + 4294972751 = 4294972780
53 + 4294972727 = 4294972780
167 + 4294972613 = 4294972780
347 + 4294972433 = 4294972780
359 + 4294972421 = 4294972780
443 + 4294972337 = 4294972780
701 + 4294972079 = 4294972780
719 + 4294972061 = 4294972780

Showing the first eight; more decompositions exist.
