Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8608378, here are decompositions:

5 + 8608373 = 8608378
131 + 8608247 = 8608378
137 + 8608241 = 8608378
431 + 8607947 = 8608378
461 + 8607917 = 8608378
491 + 8607887 = 8608378
557 + 8607821 = 8608378
641 + 8607737 = 8608378

Showing the first eight; more decompositions exist.
