Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642158, here are decompositions:

11 + 8642147 = 8642158
17 + 8642141 = 8642158
47 + 8642111 = 8642158
59 + 8642099 = 8642158
101 + 8642057 = 8642158
131 + 8642027 = 8642158
167 + 8641991 = 8642158
449 + 8641709 = 8642158

Showing the first eight; more decompositions exist.
