Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642106, here are decompositions:

7 + 8642099 = 8642106
29 + 8642077 = 8642106
43 + 8642063 = 8642106
47 + 8642059 = 8642106
73 + 8642033 = 8642106
79 + 8642027 = 8642106
103 + 8642003 = 8642106
149 + 8641957 = 8642106

Showing the first eight; more decompositions exist.
