Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294955978, here are decompositions:

67 + 4294955911 = 4294955978
109 + 4294955869 = 4294955978
139 + 4294955839 = 4294955978
367 + 4294955611 = 4294955978
421 + 4294955557 = 4294955978
499 + 4294955479 = 4294955978
811 + 4294955167 = 4294955978
919 + 4294955059 = 4294955978

Showing the first eight; more decompositions exist.
