Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294997900, here are decompositions:

19 + 4294997881 = 4294997900
103 + 4294997797 = 4294997900
139 + 4294997761 = 4294997900
163 + 4294997737 = 4294997900
241 + 4294997659 = 4294997900
313 + 4294997587 = 4294997900
409 + 4294997491 = 4294997900
439 + 4294997461 = 4294997900

Showing the first eight; more decompositions exist.
