Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642848, here are decompositions:

29 + 8642819 = 8642848
101 + 8642747 = 8642848
197 + 8642651 = 8642848
257 + 8642591 = 8642848
281 + 8642567 = 8642848
359 + 8642489 = 8642848
419 + 8642429 = 8642848
659 + 8642189 = 8642848

Showing the first eight; more decompositions exist.
