Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749298, here are decompositions:

79 + 8749219 = 8749298
157 + 8749141 = 8749298
211 + 8749087 = 8749298
307 + 8748991 = 8749298
409 + 8748889 = 8749298
421 + 8748877 = 8749298
457 + 8748841 = 8749298
487 + 8748811 = 8749298

Showing the first eight; more decompositions exist.
