Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642050, here are decompositions:

17 + 8642033 = 8642050
23 + 8642027 = 8642050
47 + 8642003 = 8642050
59 + 8641991 = 8642050
101 + 8641949 = 8642050
167 + 8641883 = 8642050
233 + 8641817 = 8642050
269 + 8641781 = 8642050

Showing the first eight; more decompositions exist.
