Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294997780, here are decompositions:

19 + 4294997761 = 4294997780
43 + 4294997737 = 4294997780
127 + 4294997653 = 4294997780
193 + 4294997587 = 4294997780
379 + 4294997401 = 4294997780
397 + 4294997383 = 4294997780
457 + 4294997323 = 4294997780
499 + 4294997281 = 4294997780

Showing the first eight; more decompositions exist.
