Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978720, here are decompositions:

41 + 4294978679 = 4294978720
59 + 4294978661 = 4294978720
167 + 4294978553 = 4294978720
359 + 4294978361 = 4294978720
509 + 4294978211 = 4294978720
563 + 4294978157 = 4294978720
587 + 4294978133 = 4294978720
653 + 4294978067 = 4294978720

Showing the first eight; more decompositions exist.
