Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294973978, here are decompositions:

67 + 4294973911 = 4294973978
79 + 4294973899 = 4294973978
109 + 4294973869 = 4294973978
307 + 4294973671 = 4294973978
349 + 4294973629 = 4294973978
367 + 4294973611 = 4294973978
409 + 4294973569 = 4294973978
439 + 4294973539 = 4294973978

Showing the first eight; more decompositions exist.
