Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642152, here are decompositions:

5 + 8642147 = 8642152
11 + 8642141 = 8642152
41 + 8642111 = 8642152
53 + 8642099 = 8642152
89 + 8642063 = 8642152
149 + 8642003 = 8642152
269 + 8641883 = 8642152
419 + 8641733 = 8642152

Showing the first eight; more decompositions exist.
