Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294958978, here are decompositions:

97 + 4294958881 = 4294958978
367 + 4294958611 = 4294958978
439 + 4294958539 = 4294958978
577 + 4294958401 = 4294958978
907 + 4294958071 = 4294958978
967 + 4294958011 = 4294958978
1021 + 4294957957 = 4294958978
1039 + 4294957939 = 4294958978

Showing the first eight; more decompositions exist.
