Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642224, here are decompositions:

83 + 8642141 = 8642224
113 + 8642111 = 8642224
167 + 8642057 = 8642224
191 + 8642033 = 8642224
197 + 8642027 = 8642224
233 + 8641991 = 8642224
443 + 8641781 = 8642224
491 + 8641733 = 8642224

Showing the first eight; more decompositions exist.
