Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642100, here are decompositions:

23 + 8642077 = 8642100
37 + 8642063 = 8642100
41 + 8642059 = 8642100
43 + 8642057 = 8642100
67 + 8642033 = 8642100
73 + 8642027 = 8642100
97 + 8642003 = 8642100
109 + 8641991 = 8642100

Showing the first eight; more decompositions exist.
